The computer does not see the Transcend microsd. Find out if the USB port is working or change the connector. Why doesn't the computer see the memory card?

Question from a user

Hello.

Tell me about one problem... I connect my phone (a regular smartphone with Android) to the USB port of the computer. There is a connection sound, the phone is charging, but I can’t log into it and copy files, the PC doesn’t see it! What can I do (I have already rearranged the drivers twice, downloaded the official ones from the manufacturer’s website)?

Good time!

The reason for the problem you described is most typical for incorrect Android settings (by the way, in the vast majority of cases this is true). For example, in the phone settings there is no checkbox indicating that the device should be connected as an MTP (media device with which you can exchange files).

Actually, in this article I will analyze this reason and some of the others that are most often encountered in everyday work. So...

Reasons and solution for phone “invisibility”

1. If the phone is charging from the port and you hear a sound when connected

1) Settings for USB connection to a computer

The first thing you will notice is the notifications that appear on the phone screen immediately after it is connected to the USB port. By default, the phone is not always immediately visible in Windows - very often, if you do not specifically allow sharing files with the device, it will only charge (like the author of the question).

A notification in Android pops up immediately after connecting it to USB - you need to open this notification (title “Device connected”). See example below.

1. The device can operate in MTP mode - i.e. an option that allows you to exchange files with it (which is what we need);
2. in charging mode: i.e. except for charging the phone, other functions and settings will be unavailable;
3. camera (PTP): allows you to transfer photos using special. software.

Actually, just check the box next to “Media device (MTP)” - ideally, you should immediately hear the sound of connecting a new drive in Windows, and in “My Computer” (Explorer) you will see your device. Mission Complete?!

2) The device is in modem mode

Go to settings at: "Wireless networks → More → Modem mode". In this section you need to disable all options for operating the device as a modem.

The fact is that when you turn on the mode, say USB modem, the device cannot simultaneously act as a modem (sharing the Internet on a PC) and exchange files with it, like a flash drive...

3) Try running USB debugging

Very often the USB debugging tool helps solve the problem. This feature is built into Android. True, there is one peculiarity: it can be “a little” hidden from view. Below I will consider options on how to launch it.

4) There is no driver for the USB root hub, for the phone

Another popular reason for a phone being “invisible” is the lack of drivers. Moreover, there may be no drivers for both the computer’s USB hub and the phone itself (even the newfangled Windows 10 is not able to recognize and automatically install drivers on some types of phones).

To view the driver status - open device Manager (to do this, you can use either the Win+Pause button combination (and then see the menu on the left) or the Windows control panel) .

In Device Manager, expand the USB Controllers tab and see if you have a USB hub. I recommend right-clicking on it and selecting from the pop-up menu "Update driver" and follow the instructions of the master (Important! Try both automatic and manual update options! Often, with the manual option, you can choose from several driver versions - try different ones) .

Remark!

In general, ideally, it would be better to launch a special one. utility for a comprehensive driver update and check your system with it. For example, Driver Booster allows you to do this in minutes:

Please note that if the driver is installed on your phone, then in the “Portable Devices” section you should see the name of your device (most often just its model).

2. If the phone is not only not visible, but also does not charge from the USB port (does not show signs of “life”)

If nothing happens when you connect your phone to the USB port, then it is obvious that there is no contact (no power is supplied from the USB port to the device). Most often, in this case, it is necessary to look for hardware reasons for this behavior: for example, the cable may be broken, the micro USB port of the phone may be broken, etc.

Below I will go through the most likely reasons...

1) Is the phone itself turned on?

Maybe this reason is too “banal”, but if you have a new phone or the battery is discharged to such a state that the device simply turns off, then connecting it to a USB port will only charge it! Until the battery reaches 5-10% charge, usually the device does not turn on and you will not be able to log into it.

In this case, all that remains is to wait for the device to be sufficiently charged...

2) Are the battery contacts sealed with tape...

This option applies to new phones and batteries. If your device is new, check its battery contacts. Its inoperability may be due not only to discharge, but also to the fact that the battery contacts may be sealed with tape. Manufacturers do this for safety reasons during transportation.

The battery contacts are sealed with tape

3) Is everything ok with the USB cable?

Next, pay attention to the cable with which you connect the device to the PC: is everything okay with it? Often, due to frequent use, the thin copper wires in the cable itself are damaged (that is, the cable may look completely intact on the outside, but be broken inside).

Therefore, try connecting another device using the same cable (you can use another PC/laptop). Goal: check the cable itself to see if it works...

4) Is the computer’s USB port operational?

The same applies to the computer’s USB port: try connecting another phone, flash drive, etc. to it. Does the computer see them and can exchange files?

Also note that system units, in addition to the front panel with USB ports (to which most users connect devices), also have USB on the back wall. Try connecting your phone to them.

Remark! It’s not uncommon to forget to connect the front panel with USB ports and audio jacks.

5) Test your phone by connecting it to another PC, laptop

It would be a good idea to check the phone itself with the USB cable by trying to connect it to another computer. Purpose: to verify the functionality of the device itself and its micro USB connector.

6) Is there enough power (is a USB splitter installed)

Well, the last point that is worth paying attention to: are you using various USB splitters and extension cables? It is not uncommon to add a USB port to a keyboard, mouse, speakers, monitor, etc.

The fact is that when using various splitters, there may not be enough power for your phone (this often happens with external hard drives). If you want to connect many devices to one USB port, then use splitters and hubs that have an additional power source (as in the photo below).

PS

Please note that if you connect your phone to USB only to transfer some files or photos from the device’s memory to your PC’s hard drive, then I recommend trying alternative methods. For example, files can be transferred over Wi-Fi, using network drives, flash drives, etc.

Thanks in advance for any additions...

And that's all, good luck to everyone!

Hello, dear friends. In this article we will look at how to recover a memory card and how to restore an sd without much difficulty. This is a very pressing issue nowadays. Now almost any new electronics has a slot for a memory card of some type. The most popular formats are microSD, miniSD, SD.

Progress of memory card resuscitation

1. To recover various data from SD, you need to install special software on your personal computer. It can be either free or cost some money.
2. Then, using a card reader, you need to connect the memory card to a personal computer.
3. Launch the program and, following the assistant's prompts, recover deleted data.
4. Finish by saving the data to your hard drive.

This is not difficult. To transfer files from SD, various software will help you. It is recommended to have it on hand in case of data problems. This way you don’t spend a lot of time and you don’t need special skills. It is best to try to revive the card using the software suggested below.

SD Card Recovery Software

The most common program for recovering data from micro SD and SD is SD Card Recovery. This is a free program and it won't be difficult to find. It allows the user to recover deleted information from various flash cards. Files will be restored quickly.

SD Card Recovery is a modern utility, it is easy to learn and does not require special knowledge in the field of computer technology. It supports the following formats - micro SD, SD, MS, M2. Another feature of this utility is the recovery of information from damaged flash drives. It can recover files in mp3, mp4, jpeg, etc. formats. The recovered file will be returned to you without distortion. Restoring a micro SD flash drive using this utility is not difficult. Absolutely everyone can figure this out. To date, SD Card Recovery software has received many positive reviews from various users.

R-Studio program

Also, another free software that can help you with SD resuscitation is R-Studio.

On the official web resource they write that this program is not difficult to learn, but is capable of restoring a large number of files intact. It is an excellent substitute for SD Card Recovery.

Easy Recovery

Another means of returning files from a card is Easy Recovery. Some professional users praise its file recovery capabilities.

There are some problems that may arise when recovering data. Each of us can face them. Let's look at several ways to solve such problems.

If MicroSD is not detected

There may be several options.

Option 1. Sometimes your PC does not see the memory card, but how will you restore it then? There are 3 ways to solve this problem. Sometimes the flash drive is displayed with a letter. To solve this, you need to open Disk Management. To quickly open this window, you usually use the Win+R key combination. There you need to enter the command diskmgmt.msc. In the window that appears, select the flash drive, and then you need to select “Change the drive letter or path to it.” Then select another letter and save the changes.

Option 2: Often, after purchasing a new computer or updating the software, it may lack the necessary drivers. You need to install them. You need to go to the corresponding official website and find this driver there, and if you have a distribution kit on any medium, then use it. Drivers will help you identify connected devices on your computer. This is one of the easiest ways to fix the problem.

Option 3. The easiest way is to disconnect the flash drive and connect it to another device. This is not the best method, since you need to solve problems on the main computer before restoring the flash drive, but this method is the least time-consuming.

What to do if the PC does not see the flash drive or entire files? This means that your PC does not see the flash drive only partially (some files are present, but others are not). Many people think that their flash drive is broken and are trying to restore it. There is no point in drawing hasty conclusions. You can try to solve this problem by running a virus scan. Viruses can interfere with the normal operation of a flash drive. You need to insert it into your computer and check it with any antivirus.

Formatting SD and microSD memory cards

If it was not possible to recover data from the memory card, then it needs to be formatted for further use. There are times when, while using a flash drive, there is not enough space, and you urgently need to load files onto the flash card. When solving this problem, it is advised to copy all the files that were on the card and then format it.

There is also a situation when your personal computer or mobile device does not see the memory card and requires formatting it for further use of the flash card. If your memory card cannot be read after this procedure, then it is most likely broken. What to do if the memory card is damaged? Is it possible to restore it? A damaged memory card can be taken to service. There, with rare exceptions, they will help you restore a damaged flash card. Repairing a memory card can cost a lot of money, and there is no guarantee that all data will be restored. In the next paragraph we will look at how you can restore a microSD card at home.

Restoring a memory card can also be done at home. How to recover a flash drive? To recover a microSD memory card, the Hetman Partition Recovery program can help you. This is a program for recovering an SD card. This software allows you to find previously created disk partitions that were subsequently deleted. If your flash card cannot be read, then you can try this method. This program for microsd and sd recovery is suitable for use even by inexperienced and novice users of modern technical devices. Now you should not have any questions about how to recover an SD memory card.

Devices that will help with formatting

A personal computer is the most reliable device. It can be used to perform various actions with portable devices. To connect various types of cards (SD and microSD) to a computer, we need a card reader that will help the PC identify the memory card as a regular flash drive.

There is another way to connect and identify SD and microSD on a PC. This can be done using a cable that needs to be connected to your tablet/phone. For example, you have a memory card in your tablet and you want to open it on your computer. Connect your tablet and PC. The flash card will appear as a regular additional storage medium.

If your device (phone or tablet) does not have the function of formatting a memory card, then in this case you can use separate programs on your PC.

How can you format a flash card?

There are many programs that have this function. One good program is SD Card Formatter. She, like the others, will not be difficult to find. Let's figure out what SD Card Formatter is.

This formatter is free. The program will help you format various types of flash cards. The most common function of SD Card Formatter is SDXC and SDHC formatting. This program has many useful features, one of which is formatting flash drives by connecting Android devices to a computer. This flash drive recovery program is easy to learn.

How do you format microSD cards? Formatting a microSD is no different from formatting a regular SD, as is restoring a microSD memory card from an SD. This is done either using a computer with a microSD-SD adapter, or using your portable device that supports microSD.

Knowledge that will definitely come in handy

To avoid problems with SD, you need to take proper care of it from the very beginning. If you follow these points, then there should be no problems. Let's consider simple rules:

• There is no need to subject the flash drive to physical impact (do not drop it);
• Try to defragment the SD card;
• Periodically copy the contents of the drive to another medium, such as a computer. In the event of a malfunction, you can format the card and transfer the data back;
• There is no need to fill your memory to capacity. You must have at least 10-15% free space;
• You should try to remove the memory card rarely, and only using a special function that is available in new smartphones (Settings>Memory>SD Eject);
• Your flash drive should not lie idle; try to use it periodically.

Restoring a microSD card, of course, is not difficult. But the main thing is to take care of your storage media so that such problems do not arise in the future.

Android does not see the microSD flash drive (memory card) September 2017

What to do if Android does not see the microSD flash drive? This question often worries owners of smartphones and other gadgets, regardless of manufacturer and cost. Problems of obtaining data from a DVR or installing software on a tablet or smartphone can be solved independently if you know the main causes of the malfunction and how to solve them.

How the problem manifests itself

Virtual reality glasses

The most modern VR glasses for iPhone and Android smartphones, as well as for computers.

The malfunction manifests itself as follows: after replacing the micro-SD card, after rebooting, flashing or simply turning on the device, the gadget does not see the flash drive or its contents. As a result, data or installed software is lost, the camera and programs begin to write information to the internal memory of the device. The latter quickly becomes clogged, there is no space left for recording OS service information, and the gadget loses performance and begins to freeze.

As a result, if the internal memory is small, it becomes impossible to work without a memory card.

To fix the problem, you need to determine the cause of the breakdown. Very often it is possible to eliminate a defect yourself, without going to a workshop.

The phone does not see the flash drive due to formatting problems

The partition table can become corrupted on any file system (NTFS, ExFat, Fat32). As a result, Android cannot read files written to SD. Most often this happens when the user tries to format the memory card himself and performs incorrect actions. Another option is to insert a card with a different file system, for example, from a camera. You can restore the card's functionality by formatting it again. This can be done either with the phone itself or another Android device, or using a computer with a card reader.

The menu of some phones allows you to format the SD card by selecting the appropriate item in the settings. If it is not there, you can reboot the phone, enter “Recovery” mode and format the file system of the card by selecting “Wipe cache partition”.

Important: errors when working with the device in “Recovery” mode can lead to the loss of all data and even inoperability of the OS. Therefore, inexperienced users should not use this method.

It is easier and safer to format flash drives on a computer. To do this, you need a card reader and a formatting program (standard, built into the OS, or any other). You need to remove the flash drive from the device, insert it into the card reader and format it in exFAT or FAT32 format. After formatting, Android should begin to “see” the flash drive. If this does not happen, the problem is more serious.

The memory card has failed

Flash memory has a limited number of read-write cycles. In addition, the device may be damaged due to microcracks on the board or under the influence of static voltage. In this case, after installation in the card reader, the computer does not detect the flash drive. It is also not readable on other devices.

It is impossible to restore a damaged memory card or the data on it. This cannot be done either from the Android device itself, or by connecting it to the computer as a flash drive via USB, or from the computer via a card reader. All that remains is to purchase a new flash card compatible with your device.

Important: sometimes, due to a board malfunction, phones and tablets can “burn” memory cards. Therefore, if a short time after replacing the flash drive it fails again, it is necessary to diagnose the Android device.

Memory card and Android devices are not compatible

A smartphone or tablet may not see the flash card if it is simply not designed to work with modern storage media. When there is a suspicion that the card does not correspond to a tablet or phone, then you should try to read it on a computer with an adapter for memory cards. If the gadget does not see the card, but the computer does, the reason is incompatibility.

All gadgets have restrictions on the maximum size of the memory card: 16 GB, 32 GB, 64 GB, 128 GB. This happens if, for example, you bought a 64 GB card, but the limits of your smartphone (tablet) are 32 GB.

Another option is that the flash drive is made to a technical specification that is unknown to your device. In this case, the gadget does not recognize it. Therefore, before buying a memory card, you need to study the documentation of your tablet or phone to buy an SD card of the appropriate size and type.

In addition to incompatibility, device damage or software failure may occur. In this case, the computer will also see the flash card, but the phone (tablet) will not.

Software error

In this case, the gadget either does not see the memory card at all, or certain programs do not see it. If you know - the card is empty, although it shows that the space is occupied, the problem is in the settings or performance of the OS and software of the phone (tablet). If Android does not see the SD card in applications, but does see it in recovery, try looking at the settings first. It is possible that the save path for applications is not set to the card, but to the internal memory. Fix it.

Another solution when only one application does not see the card is to reinstall or update it, and also check its own settings.

Important: often the phone OS begins to see the inserted card only after a reboot. If the flash card is not visible without rebooting, and then works fine, nothing else should be done.

When the above does not help, you should try updating the firmware of your tablet (phone). Often, after updating the OS to a newer version, the device begins to work correctly with the SD card.

Broken SD card slot

If a smartphone does not see a flash drive installed from another smartphone, and it meets the technical requirements of the device, the problem is in the smartphone itself. In this case, you can try to insert the card so that the contacts in the phone fit tightly to its tracks. To do this, you should try to clean and bend them a little. If the problem is not with the contacts, but with damage to the controller or card slot, all that remains is to send the gadget for repair or replace it with a new one.

For example, the HTC srochnyi-remont.ru workshop repairs all models of this manufacturer, as well as other brands. Look for a service center for your phone in your city.

Recovering a MicroSD memory card

The problem of MicroSD recovery is now more popular than ever, and is in great demand. Flash drives often break, but half the trouble is when it just breaks; the second “bad” part is that the information on it is also lost, which is undesirable. This is why questions are often asked on the Internet about how to even get information from a broken flash drive.
The problems with this can be very diverse, some simply cannot recover the media, while others produce errors. Especially for recovery, there are special programs for restoring MicroSD cards. The user only needs to point to them.

1. MicroSD recovery programs

ColdRecovery does an excellent job of restoring photos, audio recordings, videos, and more. The program cannot recover regular files, so it is suitable only for those media that are used on cameras, phones and music players.

How to use CardRecovery:

1. Download the program. We launch and continue the actions with the “Next” button.

2. Select “Drive Letter” in the special section, and then select the device type “Camera brand and...”, where we check the required boxes next to them and specify the folder for data recovery. "Next".

3. Wait for completion and “Next”.4. We look at the list of recovered files. Check the box next to the ones you want to save. "Next" again. The restoration is complete.

PC Inspector Smart Recovery

The program is superior to the previous one in its functionality; it will restore all required, available file types. It can also work to restore fixed and removable hard drives. It's easy to use: 1. Loading Smart Recovery;2. In the start window, select the desired item, in our case it is “recovery of logical files”. 3. Select the required disk.

On the forums and the official website they write that this software is the most “comprehensive”, and it will restore most of the files intact. Users agree to this. To recover data using R-Studio, you need:1. Download R-Studio to your PC.

2. Select the “Drivers” section, where you will need to select the media from which the data will begin to be recovered. The Properties section should now start displaying the properties of the object being restored.

3. The next section “Folders” shows the folders, and the other “Contents” shows the data (files) of this folder. To restore them, you will need to click on the “Recovery” item.

Many professional users praise the program and its file recovery capabilities. There is only one way to check the functionality of file recovery from Easy Recovery: 1. Install it before downloading.

3. Click “Continue” again. Next, go to “Data Recovery”, and check the box under this item.4. “Continue” again. Now all that remains is to wait for the process of scanning all deleted files and compiling a list to complete. Each file can be recovered separately. Select it, right-click on it and select “Save as...”.

Flash Memory Toolkit

Functional file recovery program. It can perform a variety of functions, including testing and destroying any information, backing it up and obtaining additional data. To restore data, select the desired flash drive in the “Device” section, look for the “File Recovery” item on the left and follow the software instructions. This may happen so that the restoration of microSD using the programs provided above is not always successful.

2. Possible problems with MicroSD recovery

MicroSD not defined

It happens that the MicroSD card needs to be restored, but the PC simply does not see it. If this happens, there are three options to solve the problem at once: 1. If the flash drive is designated simply by a letter when connected. Then you need to open the “disk management” program, to call it you need to enter the command in a special execution field called up by the Win + R key combination, and enter the command diskmgmt.msc into it. Select the flash drive, and then click “Change the drive letter or path to it.” After which you will need to select any other letter of the alphabet and save the changes.
2. Lack of drivers. In some cases, a new PC may simply not have a special driver for the media. The solution is to install them. This is best done through off. Website. Of course, a special Driver Pack “DriverPack Solution” may be a good option. It can independently detect all devices connected to the PC and install or update drivers for it. This method is very attractive and convenient, since in this case there is a minimum of user actions.
3. The last option is simply to disconnect this flash drive and connect it to another device, which will give you a chance to read the files on it, or restore them using software.

The computer does not see files on the MicroSD flash drive

This means that the computer does not see the flash drive in its entirety, but only partially, that is, some files are there, others are not. Often, users immediately come to a simple conclusion - the problem is in the flash drive and it needs recovery, but the problems are most often much simpler. The solution to this popular problem is as follows: viruses, most often Trojans, need to be removed. Indeed, the Trojan may hide some or all files. Therefore, just turn on the flash drive in your PC and scan it with an antivirus.

3. MicroSD cards. Restoration from different manufacturers.

MicroSD Transcend recovery

For such cards, manufacturers have created their own original software for recovering lost files. The software is called RecoveRx. The provided software takes into account all the features of the map, and is also capable of performing a number of functions better than any other programs. RecoveRx can format the microSD and also set a password on it.

MicroSD Transcend Recovery

1. Naturally, download the program from the official website.2. Select the required file types.3. Wait for the end of the process.

MicroSD Kingston recovery

The problem with this manufacturer is the Phison controllers. Which means that only low-level restoration can be done. Other methods simply will not bring results. 1. Determine the Product ID and Vendor ID parameters to find the best utility. This is done using another program - USBDeview. Open the software and find the required card on the disk. Right-click and select “html report: selected elements”. Scrolling the window below, we see the two required IDs.
2. Go to the website flashboot.ru/iflash, then enter special parameters into the required fields. As a result, you will see all the problems that have ever occurred with a specific card model. MicroSD Kingmax recoveryKingmax has acquired its own software. In general, there are two programs - one is PD-07 and U-Drive, and the other is Super Stick. Their use is as simple as possible: start - select a drive.

MicroSD Sandisk recovery

Users note that in case of any problems, Sandisk will only help with full formatting. After which the flash drive works as if it was just purchased. The program is also very easy to use.

MicroSD Smartbuy recovery

This is a very interesting manufacturer with “unique” flash cards. In the case of SmartBy, if the flash drive suddenly stops working, then after some time (a day, a week, a month, up to a year), it can independently start working again. But if you don’t want to wait, then you can try to restore it with special programs. There is a program called “DiskInternals Uneraser” specifically for such flash drives. The application looks like a regular folder. Select the desired media and click on the “Recovery” button, also known as “Recovery”, you can restore files at the end of the process.

MicroSD Qumo recovery

Qumo flash drives are notorious for stopping working out of the blue. They just don’t work anymore and there is almost nothing concrete to identify signs of their “life.” Some experienced users suggest using “R-Studio” or “CardRecovery” programs for Qumo flash drives. But this may not always be effective. MicroSD A-Data recovery In this case, little helps. Only “Paragon Partition Manager Free” works most effectively with flash drives of this format. First, the program will ask for formatting, and then create a new partition.

MicroSD Oltramax recovery

For them, regular full formatting using a special SD Card Formatter is best.

4. Restoring damaged MicroSD

It happens that when using the drive, an alarming message “Memory card is damaged” or something else may appear on your screen. The following programs will come to the rescue:

Smart Data Recovery – will help you select the media and click the “Find” button, after which it will search for the necessary files that can be recovered.

- Recuva – after launch, click “Analysis” and wait for the process to complete.
- BadCopyPro – select Memory card, and click “next” twice.
The same operations can be performed on a tablet or phone on the Android platform. Other applications will come to the rescue here:

GT Recovery for Android – select the desired item in the program and wait for completion;

-Wondershare Dr. Fone for Android – launch the program, select the required files.

5. Prevention

It is best to start using the flash drive correctly so that no bad problems occur with it. Here are some tips that will help you avoid breakdowns: 1. Try not to drop the flash drive, hit it, bend it, or generally subject it to harsh physical impact.2. Avoid various types of radiation, including X-ray machines and exposure to direct sunlight.3. Do not touch the contacts with your fingers and try to keep them closed at all times.4. From time to time, completely defragment the flash drive and use it as often as possible - flash drives do not like to sit idle.5. Create backup copies of the flash drive so that in case of malfunctions you can restore it.6. Leave free space on your storage device.

7. If the card is installed in a smartphone, tablet, or speaker, try to remove it from there less often.

If such a situation arises, when the computer is connected via a USB connection, the ability to move files from one device to another is lost.

The same problem also makes it impossible to flash the smartphone to get new features or restore functionality.

In order to solve the problem and restore the ability to connect your phone and PC, you first need to determine the cause of the problem.

And this can be done by first checking the functionality of the cable with which the connection is made, then the drivers, and, finally, the .

Priority user actions

Sometimes the problem can be solved within a few seconds. So, for example, it may disappear if the mobile gadget is blocked - both before and after connection.

Basically, when connecting, the computer automatically detects the new device, and a corresponding message appears on the smartphone with (or another operating system).

It is possible that the problem will be resolved if you connect to an unlocked phone.

In addition, in most cases, they automatically connect to the computer in charging mode.

This can be determined by the USB connection symbol at the top of the phone screen.

By clicking on it and selecting another mode (for example, "Media device"), a connection can be established to exchange data.

Rice. 2. Modes for connecting a smartphone to a computer.

The second reason, which can be eliminated in just a few seconds and a couple of taps on the smartphone screen, is.

Naturally, you cannot enable such a function by accident.

If the phone was used as a modem, to connect it to a PC and exchange files, the mode must be turned off.

And finally, the third option to solve the problem is to enable the debugging mode, which is required to connect to a computer on some phone models.

USB problems

The next step is to check the functionality of the cable that connects the smartphone to the computer. The problem may be that this part is worn out.

Situations often arise when the USB cable continues to charge the phone, but is no longer able to provide a connection.

The same can be observed when connecting using not a proprietary cable, but an inexpensive analogue.

You can determine whether the cord is the cause or whether the problem should be looked elsewhere by performing the following types of tests:

• connect another device to the same computer port - for example, a mouse. If they work, then the problem is not with the connector. But if there is no response from new devices, the user will have to resolve the issue with a faulty USB port. And connect to other slots;
• connect the same smartphone and cord to a second computer or. The absence of connection problems confirms the hypothesis of a malfunction on the PC side. If the problem recurs, the cause is the cord or the phone;
• use another cord (if available), the performance of which is not in doubt. If there is no connection, the old cord is most likely working.

Rice. 3. Damaged USB – microUSB cable.

In some cases, cleaning the cable from dirt and dust (on each side) that can get into the connector helps solve the problem with the cable. Because of this, the cord can only charge the phone.

The cleaned cable connector is reconnected to the computer.

If nothing happens, the wire is most likely damaged.

After checking it again for a different connection option - for example, from a PC or another smartphone, or another PC - and making sure that it is not working, you should throw away the cable.

And the problem with the USB connector can be solved either by replacing it (more expensive and longer, but more convenient), or by using other connectors.

Important: You can also clean the connector on your phone. However, this should be done even more carefully and carefully than when working with a cord or computer. And in some cases, such cleaning is best done at a service center.

Driver problems

A common reason for the lack of connection between a computer and a smartphone is incorrect operation of the drivers or their complete absence.

This often happens if you connect to a PC that has not previously been connected to the same operating system.

And, if automatic connection does not occur, the user will have to configure the connection manually:

1. Connect your phone to your computer;
2. After a message appears about the impossibility of installing the driver, go to the device manager (“Start”, properties of the item “Computer”);
3. Find an unknown device in the list that opens (usually indicated by a yellow triangle);
4. Open the properties of the smartphone and try.

If the driver is installed, but the phone still does not connect, you should move on to other steps to solve the problem.

But, if the installation still does not happen - even manually - you will have to use the Internet and find suitable control programs by the name of the phone.

As a rule, the manufacturer stores such drivers for new models in the public domain. The old ones can be found there - or on thematic forums.

Outdated operating system

The cause can be identified almost immediately if the user's computer has an outdated operating system.

All attempts to establish a connection with a device running Windows 2000 or 98 platforms will not lead to a positive result.

And for Windows XP you will have to download from the official Microsoft resource and install a special MTP protocol on your computer.

Despite the fact that most modern smartphones run on iOS or platforms, equipment with other OSes also remains functional.

Advice: You should not use an antivirus program that is already installed on your PC and has proven to be ineffective. A good option would be “disposable” utilities like Dr. Web. Curelt or Kaspersky Virus Removal Tool.

Checking your system for viruses won't hurt, even if the reason for the lack of connection was not malicious code.

And while the antivirus program scans your computer, you can perform the same scan on your phone (for example, using free antivirus programs from).

Although the likelihood that the problem with the lack of communication is very small, these programs do other things.

There are quite a few reasons why the computer does not see the smartphone. Most often this occurs due to the activation of any other connection mode other than a USB drive. Or this happens due to missing or conflicting drivers. Less commonly, the cause may be various malfunctions in the equipment.

This material presents solutions to the most common problems that arise when connecting a mobile device to a PC via USB. For convenience, all tips are divided by importance.

The smartphone is not detected as an external drive

Note:The smartphone must be turned on; if it is locked with a pattern, you need to unlock it!

The very first and obvious action is to let the computer understand in what mode the device is connected. If the smartphone simply charges when the cable is connected, it may be connected in charging mode, or as a media player. If you are using an Android device, you must activate developer mode and then enable USB debugging.

For instructions on how to activate developer mode and USB debugging, see this video.

When everything is done, the next time you reconnect, pay attention to the display and notification shade on your smartphone. A notification should appear asking you to select “Enable USB storage.”

If you use a smartphone with a different OS, everything is the same. In most cases, in order for the device to be recognized as an external drive, you must select the correct connection type.

One more thing: check if the modem mode is activated on your mobile device. We go to the network settings settings, and if the modem is activated, turn it off.

The computer doesn't respond at all

It is advisable to check the serviceability of components as early as possible to save your own time. If you don’t hear a characteristic signal when connecting, the charge indicator on your smartphone doesn’t blink, the backlight doesn’t activate, or pop-up notifications don’t appear, we try to temporarily change the equipment.

Steps to be taken:

1. Check the USB cable for serviceability. We just use a different working cable and that's it.
2. We connect to other connectors. Inoperative USB ports can only be referred to if no “USB” peripherals connect to them at all: mice, keyboards, flash drives, etc.
3. We are trying to connect the smartphone via USB to another system unit or laptop. If it works, we look for problems with the drivers and operating system on your PC.

Software problems

Let's say the computer responds to the device, but a notification appears on the taskbar that the driver installation failed. This indicates the need to install the “correct” USB drivers on the PC.

Often, universal drivers can be downloaded from the manufacturer's website. For example, on the official websites of Samsung and LG there are special sections where you can download a driver that will fit all Samsung and LG models, respectively.

If you have connected many devices from different manufacturers, their drivers may conflict. Try to remove unnecessary ones and install the necessary ones again. Don't forget to restart your PC (you can do your phone at the same time).

If nothing helps at all

In the event that after executionabsolutely everyone recommendations the computer does not see the smartphone, we cannot exclude the fact that the USB connector on the smartphone is faulty. Without special skills and certain equipment, this problem cannot be solved on our own. It is necessary to take the mobile device to a service center or to a workshop where the USB will be resoldered.
