The phone does not connect to the computer. The computer does not see the phone via USB, but the Android is charging. Video: fixing phone connection problem via USB

Connecting via a USB port is one of the most popular methods today. fast transfer data. You can also simply charge the connected device using a USB connection. Such functions are in demand, so these days almost everyone has one, or even several, flash drives, a smartphone or tablet connected via a USB port, and various accessories ( smart watch, MP3 players, etc.), which also connect to the PC.

Naturally, with such a variety of devices, some errors are bound to occur. They are mainly divided into two categories: identification errors, which this article will be about, and formatting errors, the solution to which you can read about.

Recognition errors are also divided into two groups: an error in which the USB device is not recognized, and an error in which the computer does not respond to this after connecting the device.

“USB device is not recognized” - what to do in Windows 7, 8

Any computer can suddenly throw one of these an unpleasant surprise with any device: USB drives, smartphones, tablets, computer mice, keyboards, accessories, printers, scanners... With everything that can be somehow connected via USB, this problem can arise, but for almost any device this error can be solved in the same way.

The first thing to do when Windows does not recognize the device is to check that it is working properly. Connect the gadget to another PC or laptop. If the error remains on another device, then the whole problem is in the device itself (or the cable through which you connect it) and, most likely, nothing will help you other than going to the store for a new analogue.
Also try connecting the device to a different USB connector, temporarily disconnecting unnecessary equipment. If nothing works, then move on to the next paragraph.

Go to Device Manager. Press Win+R and enter the command devmgmt.msc. In the window that opens, try to find your device (it will be located either in “ USB controllers", or in "Unknown devices). If it happens to be in the “Unknown Devices” tab, right-click on it and update the drivers. If the gadget is included in the “Controllers”, then right-click on it again, go to “Properties” - “Driver” - “Update”. If the update button is not available, then go back to the manager and click “Delete”. After that, open the “Action” tab and select “Update hardware configuration”, after highlighting your USB device.

The above algorithm of actions usually works both when a regular flash drive is not recognized, and when when connecting the phone to a computer “ USB device not identified."

The computer does not see the USB flash drive

Firstly, your personal computer most often does not detect the flash drive because it is faulty. To check this, insert the USB flash drive into another device. If it does not work and is not muted, then feel free to buy another flash card.
Secondly, check the connector for dirt. Naturally, if banal dirt gets into the flash drive connector, it will not work correctly.
Thirdly, try inserting the flash drive into another slot on the computer (usually there are several of them).
Next, try formatting your flash drive to match your computer’s file system. You can see what file system is on your PC by going to properties local disk. Now you just need to specify what file system you need when formatting.

Phone is not detected via USB (Android)

A smartphone is usually connected to a PC in order to transfer data and files to it that are difficult to transfer in any other way. You connect your smartphone via special cable, but nothing happens, and Windows does not react in any way to the new connected device and simply charges its battery.
But why doesn’t the computer see the phone via USB to Android, it only charges and nothing else? How to solve this?

1. If you bought new smartphone and try to connect it to old version operating system(Windows XP, for example), which is not currently supported, you need to either upgrade to a newer OS or download Media program Transfer Protocol from the official Microsoft website, install it and restart the PC - everything should work.

2. If you have several USB ports on your computer, try connecting your smartphone through a different port.

3. Try changing the USB cable. Cable faults are one of the possible obstacles to a USB connection.

4. Check the connector of the smartphone itself. Remember if you dropped it into the water?

5. Connect your smartphone to any other device (PC, laptop). If the phone just as stubbornly refuses to work correctly, then the problem is either with it or with the USB cable. If everything works, then the whole problem is in the computer options - go to the next step.

6. Try plugging another device into the computer (flash drive, for example). If an error also occurs with other flash drives, then go to the “Control Panel” and select “Troubleshooting”. In it, click on “Device Settings”. Automatic setup will occur.

7. If the computer still does not see the smartphone, then the only thing left to do is update the drivers.

Note: Most new phones now default to charging rather than data. To check what type USB connections is used, use the simple instructions from the screenshots below.

Problem connecting a USB card to a tablet computer

Some tablets now have the ability to connect a USB drive. You insert a regular flash drive through a special adapter, the tablet does not react at all. So why doesn’t the tablet see? USB flash drive through an adapter?

The main reason for this error is different standard file systems. Then you need to format the flash drive in FAT32 (this is exactly the system designed for modern tablets) via computer.
If this does not help, then you need to root the device and download from Google Play app StickMount, through which you can install the USB drive virtually after inserting it into the tablet.
If none of the listed methods did not help, then think about repairing the tablet.

Connecting a smartphone or regular phone to a computer or laptop allows the gadget owner to move files from one device to another, and flash the latter’s firmware in case of problems. However, there are times when Windows 10 does not see the Android OS via USB and any prospect is reduced to zero. Therefore, before solving a problem with connecting a device, it is worth checking the functionality of the cable (with which the connection is made), the driver and the smartphone itself. Then make adjustments to the settings of Windows 10 itself.

Reasons why the PC does not see the phone

A computer with Windows 10 may not see a smartphone or phone for several reasons:

• The user did not give permission to connect the gadget to the PC;
• The USB cable is damaged;
• There are no drivers for working with the phone;
• Problems with the smartphone itself or any other gadget;
• Virus infection of the system;
• Outdated, incompatible version of the operating system.

Having established the exact cause of the problem, you can establish a correct connection of the gadget to the computer.

Ways to solve the problem

When you connect the gadget to a PC via a USB cable, a message appears on the screen of the first one indicating that the smartphone can be connected to the PC. Check the box to select what type of connection you need. There is a connection for the phone itself, memory card, media player, charger, camera.

This may be an option.

Only after confirming the selected action, the smartphone will synchronize with the computer and become visible.

If the computer does not see the gadget at all and does not respond to connecting the device via USB, it is worth checking the cable itself for functionality. You can do this in several ways:

• Connect the cable to another PC or smartphone;
• Use a different cable (if available).

If nothing happens, the wire is most likely damaged. After checking it again for a different connection option and making sure it is not working, the cable should be replaced.

The problem may also lie in the nest. Try reconnecting USB cable into another computer slot and look at the result. Perhaps you are using USB port 3.1, which is not suitable for of this type connections.

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 your computer new phone. And if automatic connection and the driver update has not occurred, you must configure the connection manually. To do this, do the following:

• Connect the phone to the PC.

• Go to “Device Manager”. We find unknown device(will be displayed with a yellow triangle).
• Right-click on it and select “Update Driver”.

• After searching and updating the drivers, you need to restart the PC (disconnecting the phone).

IMPORTANT! If included with the gadget disk is coming with drivers, we recommend using it when updating drivers.

If even after updating the drivers, the computer does not see the phone or does not want to connect it, you will have to find a special program on the network that is designed to work with the gadget. You should look for the program on the official website of the smartphone manufacturer.

Also, the laptop may not see the phone due to the system being infected with a virus. Malicious program can make changes to the system registry or change an important file and affect the interaction of Windows with your gadget. Therefore, we recommend checking your system for viruses.

The last recommendation would be to restart the phone or turn it on completely (removing the battery for 5 minutes or more). After rebooting the device, you should reconnect it to the system. In case you connect to the system old phone 2000, or even earlier, or you have Windows XP or 2008 installed, then the problem may lie in an outdated OS. The only option is to connect your phone to the latest build of Windows 10.

What to do if the laptop does not see the phone via USB? The reason may be several known factors that have very specific solutions.

Problems with the USB cable

Quite often, you cannot connect your device to your laptop due to a broken cable. Perhaps you did not use it very carefully, or your pets “helped” give it the proper condition. Take another known working wire from a friend, and then try to repeat the procedure. If the phone is detected, the problem is solved. You'll have to go to the store and buy new USB cable, fortunately it is quite cheap.

Glitch in port operation

An old admin saying goes: “reboot the system to make it work.” The option remains relevant to this day for everyone who owns laptops with pre-installed Windows on board. Sometimes USB ports simply glitch, and after a reboot everything goes back to normal.

Another one interesting feature– change of port. If the connection could not be achieved by inserting a cable into one port, it will certainly be possible when connecting to another. As a last resort, you will need to reinstall the native USB drivers, which come with the motherboard.

Alternatively use the path:

1. "Start";
2. "Control Panel";
3. "System";
4. "Device Manager".

If you see a problematic port marked with a question mark or a red cross, update it if possible.

The reason lies in the phone itself

So, you are sure that everything is fine with your laptop. Then the reason may lie in the connected device itself. This could be either disabled synchronization, or glitches in the firmware, or something else. The easiest way is to restart your phone and repeat your attempts.

In more advanced cases, you need to remove the battery and wait 4 minutes. In the worst case scenario, you will need to reflash the device.

Alternatively you can download special software for working the phone with a PC, like Nokia PC Suite, SE PC Companion, etc.

Virus

Trivial Trojan and malware can easily block USB operation ports, depriving the PC of the ability to connect external electronic devices. Similar problems This can often be observed with ordinary flash drives, with which we walk around the institute from computer to computer in an attempt to find some useful report.

Use the services, just first update its database to the current state, if possible. Otherwise, no one can guarantee that you will thoroughly check and eliminate dangerous contents.

The most reliable option

Unfortunately, the repair service by a professional is paid and can range from several hundred to thousands of rubles, since the breakdown can be very different: from a bug in the firmware to a burnt-out USB hub.

Possible reasons include incorrect connection actions, outdated or incorrectly configured software, malfunctions of USB cables, ports, or the devices themselves.

Follow the tips listed below, they can save you from many connection problems.

Or a tablet connected to USB? You are not the first to be affected by this problem, but do not rush to despair. Today we will try to help by talking about possible reasons that the phone is not detected by the computer. In addition, you will learn how to deal with this common “disease”.

Why doesn't the computer see the phone connected via USB?

So, all problems with connecting your phone to a computer via USB can be divided into two types:

• hardware;
• software.

We will talk about each of them, but first, a little advice that very often helps users, saving them from further actions:

We simply reboot both devices (phone and computer). As practice shows, this simple action helps with solving a lot of problems, so we resort to it first.

The computer does not see the phone - hardware problems

First, let's go through hardware problems that are often identified by users.

USB cable is damaged

As a rule, the “victims” include users who decided to save money by choosing a cheap wire from an unknown company. They can work well when paired with a power adapter, but they don’t want to be “friends” with a USB port.

The solution is very simple: try another cable that works.

However, do not rush to call the wire manufacturer bad names - check it for damage. Sometimes they are so small that they are unnoticeable. The wire may be broken at the base, chewed by pets, or otherwise damaged.

Inspect carefully USB cable to identify damage. If no problems are found, then try connecting the phone to the USB port of another computer.

The USB port on the computer is damaged

Less often, but the cause of connection problems is a non-functional USB port on the computer. Checking whether the connector is functioning is very simple: insert any other device into it, for example, a flash drive or external hard disk.

We just try to connect the phone to a different connector. Some users recommend using USB ports 2.0 (USB 3.0 blue).

Problems with the charging connector on the phone itself

Typically, problems with the phone socket begin after falls, water, dirt or other damage. If any of the above happened to your gadget in Lately, then you will have to visit a service center where specialists can replace the damaged port.

Device battery problems

Another hardware cause could be battery problems. IN best case scenario you just need to remove the battery from your phone for a few seconds if possible. At worst, you will have to replace the battery.

The computer does not see the phone - software problems

If you tried changing the wire, connecting the phone to another USB port, but nothing helped, then we move on to the software reasons, which in most cases are the culprits of the problems.

Problems with phone settings

Very often precisely because incorrect settings, which the system installs by default, it is impossible to pair the computer and phone. So:

• Check the connection mode. Smartphones at the most current versions operating room Android systems By default, they can be connected to a personal computer in charging mode. Therefore, the latter does not react in any way to pairing with a new device, but only powers it through the port.

As a rule, you can select a mode in the notification shade on your smartphone. Should appear here system message with the selected mode. Click on it to see available options. We select the mode that is associated with the transfer or access to phone files (it may be called differently depending on the operating system, manufacturer, and so on).

Sometimes the connection notification does not appear among the notifications, so you will have to find the menu with modes yourself. It is located in the phone settings (USB connection option or something similar), where you can also select desired mode with access to files on the phone.

• The phone should not be in modem mode. Often, by default, mobile devices, when connecting to a PC, start working in modem mode, which does not make it possible to access files.

You can disable modem mode in the settings wireless networks. You just need to turn the toggle switch to the inactive state opposite the desired item.

• The phone is infected with viruses. Increasingly, the cause of many problems with the phone is virus attacks, which can really cause a lot of harm. Some users have already determined that their smartphones could not connect to their PC precisely because of malicious software that blocked access.

Remove recent applications that make you suspicious. Take advantage antivirus programs to detect viruses. We recommend free utility Dr. Web CureIt!, which can be downloaded fromPlay Market .

Problems with the computer and USB ports

Quite often, the culprit of confusion can be a personal computer, or rather the lack of necessary settings or drivers, as well as various errors.

• Installing port driversUSB . If USB drivers do not work correctly or do not work at all, then the devices connected to them will not function or will start with errors.

Solved by reinstallation. Drivers must be taken from the disk that comes with the motherboard(laptop) or from the manufacturer’s official website. Installation usually does not take much time. When finished, be sure to restart your computer if the system does not do this on its own.

• USB -ports do not receive power. Some users, experimenting with hardware, accidentally or deliberately turn off the power supply to the USB connectors, which leads to understandable consequences - complete inoperability.

You need to go to the “Nutrition” section. To do this, go to “Control Panel”, “Hardware and Sound”, then “Power Options”. Here we find the item “Setting up a power plan”. We search and click on “Change” Extra options nutrition." From the list that appears on the screen, find the item “ USB Settings" and click on the plus sign opposite. You will see the “Option to temporarily disable the USB port” and also click on the plus sign located next to it. The “Prohibited” parameter should be set everywhere here. Set it up for everyone and click “Accept” at the bottom.

• The phone drivers have crashed. Another equally common reason for the phone not being detected by the computer is a problem with the drivers. This may be due to errors incorrect installation and so on. The problem is solved by a simple reinstallation.

You need to go to “Device Manager” (can be found through the search bar). Here, all devices that are connected to your computer are listed by subsection. We need to make sure that no exclamation mark opposite the section " Portable devices" If the symbol appears and your device is indicated in the item, then:

1. click right button mouse by phone name;
2. select “Properties”;
3. go to the “Driver” tab;
4. At the very bottom, click the “Remove device” button;
5. we agree with the warning;
6. disconnect and reconnect the phone to the computer;
7. We wait for the system to reinstall the driver.

It would be a good idea to visit the manufacturer’s website mobile device, where you can always download the most fresh drivers for your phone. Some even provide special programs, which help synchronize your PC with your phone and regularly update the driver automatically.

• Requires update KB3010081 (KB3099229). Some operating versions Windows systems 10 require installation of update KB3010081 for Windows player Media Player. He is directly responsible for normal work Media Transfer Protocol service, which is activated during connection.

You can find and download updates on the official websiteWindows . It extends to free of charge. After installation, do not forget to reboot the system so that the changes work stably.
