One of the devices is not working properly. The laptop does not see the USB mouse and does not respond. Reasons and what to do

Problem: an error appears when connecting a device to a USB port

USB device not recognized One of the USB devices connected to this computer is not working properly and Windows cannot recognize it.

This error can occur when connecting any device: flash drive, external hard drive, Wi-Fi adapter, smartphone, printer, scanner.

First of all, you need to try to understand whether the device is working properly. If possible, connect it to another computer. If the device works correctly on another computer, read further about the possible causes of the error.

Causes of error and solutions

1. Poor contact

This often happens when connecting old phones with old data cables, because... contacts on connectors and plugs oxidize over time and simply become dirty.

Tip: clean the gadget connector and the connecting cable plug.

2. The device is connected via a poor-quality (or too long) cable or via a USB extension cable

Most often, Hewlett-Packard printers do not work well with cheap cables (usually gray, thin and without ferrite filters). And in offices, they also love to use long cables.

Tip: use only high-quality and original USB cables. If possible, connect the device directly to the port; avoid using extension cords.

3. The additional power cable for the hard drive is not connected

An external 2.5-inch hard drive can work in half the cases without connecting an additional device. nutrition. However, to ensure trouble-free operation, it is recommended to connect both plugs.

Tip: connect additional power.

Remember that 3.5-inch external hard drives work with a power supply!

4. The device is connected to the port on the front panel

This item applies only to desktop computers, because... There is no difference in ports on laptops.

Devices that are particularly sensitive to connection quality and port voltage stability do not perform well in the front ports.

Tip: Connect the device to the back of your computer and check its operation.

5. Too many USB devices connected to the computer at the same time

This can cause both a voltage drop on the ports and conflicts between devices.

Advice: turn off all devices. Restart your computer. Connect only the problematic gadget to the port on the rear panel and check its functionality.

6. Compatibility or device driver issue

This sometimes happens when connecting old mobile phones (drivers for which are only available for Windows XP) to modern computers.

Adviсe:

  1. Make sure that the device is designed to work with the current OS. Download the driver from the official website and install it on the system. In Windows 7-10, you can try to automatically search for drivers ().
  2. Prohibit temporary disabling of the USB port.
  3. Prohibit the USB device from being disconnected.

How to prevent a port from being temporarily disabled

Open:

  • Control Panel
  • Power supply
  • Setting up the power plan (current profile)
  • Change advanced power settings.

In the window that opens Power supply:

  • Expand the item USB Settings
  • IN The option to temporarily disable the USB port select value Forbidden
  • Click OK:

How to prevent your device from turning off to save energy

  • Open device Manager (win+r, devmgmt.msc, enter)
  • Expand section USB controllers
  • Call properties USB root hub or Generic USB Hub:

  • Uncheck Allow this device to turn off to save power
  • Click OK:

These days, a computer has several USB ports to which you can connect a keyboard, mouse, and other USB devices. You can also connect a flash drive or external HDD to the USB port. After connecting the flash drive/USB drive, you may receive an error message like this: “USB device not recognized.” At this time, Windows displays a message that the USB device is not recognized in the form of pop-up notifications in the Windows taskbar area. Windows is showing an error message due to an unknown fault in the Windows operating system due to which the USB is not recognized and an error is thrown. What would you do in this case?

The error says:

On Windows 8, 8.1 and Windows 10 –
The latest USB device is not connected to this computer correctly, and Windows cannot recognize it.

or, on Windows 7

The USB device is not recognized, or one of the USB devices connected to this computer is not working properly and Windows cannot recognize it. For help resolving this issue, click this message.

When the error occurs, Windows cannot show the USB storage device in the 'My Computer' section in the File Explorer area and if you can take a look at the Device Manager in Windows, then you will find a yellow triangular alert icon near this device, which is invisible in Windows. The yellow triangular logo helps you locate the device in the Device Manager list. The photo below shows if you have never seen this error.

The error is very common and has been discussed by everyone through web portals and forums for years. No matter which Windows OS and which version of OS (it could be Windows 7 OS, Windows 8 OS, Windows 8.1 or Windows 10) you are using, you can certainly get the USB not recognized message more than once in your life. by inserting a USB flash drive or external USB drive into your PC. Actually, there is no exact and specific reason for receiving this error message. So, we have to identify the problem of such error and try to fix it manually step by step for troubleshooting. Removing a USB device is not always safe and can cause problems; there may also be another problem related to windows drivers or similar ones that cause the device not to be recognized by the system. Most of the time, users using USB and virtual Windows operating systems receive an error message, but there are quite a few cases that I have had when I connected a USB flash drive directly in the My Computer window.

How to resolve and fix the 'USB device not recognized' error in Windows 10, Windows 8.1 and Windows 7

There are probably several reasons that cause Windows to not display the device and it is not recognized causing an error, so of course there are several possible solutions. Here, follow the guide to get rid of this error. This doesn't mean you won't get the same error soon. Since there are many reasons for causing an external drive to not recognize it, thus, you can get the same Windows errors any time you plug a USB device into a Windows USB port.

Step 1: Disconnect the USB device and plug it back into the same port

Once you receive the error notification, simply remove the USB device and reinsert it. Try the same method two or three times. If you are lucky, you may be able to get rid of the Windows error that is preventing you from accessing a specific USB device. If this remedy works for you, then it may be an issue loading the device driver in Windows at the time you introduce the external USB into your PC.

Step 2: Disconnect the USB drive and reinsert it into another USB port

Try another USB port while you keep getting the error message. There may be a problem with the USB port. The USB port can get into mischief or develop mechanical problems over time. Therefore, try to use a separate USB port to solve the problem, if this helps, then it is probably a problem with the USB port. Replace the USB port immediately so that you do not receive any errors in the near future due to the same reason.

Step 3: Restart your computer to fix the problem

When you start turning on your PC, all programs, drivers, processes, services start automatically in the background. But, if any important process or driver does not load at startup, your computer may act up and may result in a “USB device not recognized” error.

Step 4: Windows Device Manager Search Problems and USB Driver Problems

This step is the most important. Most Windows users who receive this error can fix it using Windows Device Manager. In Device Manager, you can find all the connected devices of your PC, including processors, printers, hard drives (internal and external), etc. So, how to find and fix the problem of recognizing the connected external USB device using Device Manager? Follow the steps as described below:

1. Press Windows+R and open the Run window, in the window run the following command devmgmt.msc to open the device manager in the Windows window.

When the scan is completed, the program will automatically load the usb driver. If the USB device is not recognized and fixed, then, of course, this is a problem in Windows driver synchronization.

A USB device that is not recognized by Windows is marked as ‘Unknown Device’. You can update drivers in Windows by right-clicking in the context menu. You need to select the unknown or unrecognized device from the list in Windows Device Manager and right-click on it. Select “Update Driver”.

After a successful update, you should no longer receive an error message with USB devices. If the error persists, you can disable the unknown device driver for a while and give it a chance to bypass the error. But, if the message still appears, it is better to uninstall the device driver and reinstall the latest drivers from the Internet.

Now select the USB Root Hub - Properties and under the ‘Power Management’ tab you will find the option “Allow the device to be turned off to save power”. Uncheck the box and see if it helps or not.

Step 5: Disable USB - Selectively Pause Setup

There are various power options available in your computer's control panel. Select “Change Settings Plan” of your running plans and click on the “Change advanced power settings” option. Now scroll down to USB Setting >> USB Selective Suspend >> Install and force it to shut down. Laptop users should select the battery option and then make it disable.

Step 6: Change the registry to 'enhancedpowermanagementenabled' to fix the USB device issue

Many Windows 10 PC users may encounter the same problem. In addition, when connecting a device using a USB cable, the device remains disconnected. When you connect a USB device to a PC using a USB cable, the device receives charge from the PC. In this case, for Windows 10 users, when you connect the device to the USB port, the device gets charged, but the PC does not show the device in File Explorer. Sometimes, users receive a “USB not recognized” error message. The procedure to resolve the problem is described below.

Open Device Manager and go to the properties of the USB device that shows errors.
Switch to the ‘Details’ tab and select the path to the device instance from the drop-down menu.
Be aware of the corresponding instance ID.


Now open Registry Editor and navigate to the following path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\(Device Instance Path)\Device Parameters

On the right side of the device parameter, change the value of ‘EnhancedPowerManagementEnabled’ to ‘0’.

Restart your computer to receive the error message has been fixed.

Step 7: Remove existing hidden devices

Windows Device Manager does not show all devices in the list. It only shows devices connected to the PC. Devices that were previously installed and not connected to the PC right now do not appear in the Device Manager list. For example, a USB scanner after installation on a PC and if it is no longer turned on, it will not appear in the device manager list. However, some hidden devices may cause problems for modern USB devices and will result in an error message.

Now, let's see how to show hidden devices and remove them to avoid any conflict between them.

Open a command prompt as an administrator and run the following commands:

Set DEVMGR_SHOW_DETAILS=1 set DEVMGR_SHOW_NONPRESENT_DEVICES=1 start devmgmt.msc

Once Device Manager has loaded successfully, in the top navigation pane, select View >> Show hidden devices.

Now, find and manually identify the list of unused drivers and remove them. You can check unknown devices, Universal Serial Bus controllers, etc.

New devices can now work perfectly after removing old devices and drivers. Thus, we hope that you will find a solution to fix “USB not recognized” in Windows.

Step 8: Try the USB port to troubleshoot the application

If the above methods did not work and your device still does not work for you, you should try the ‘fix’ apps from Microsoft. There is also another useful tool from Microsoft to do this kind of work. The instrument known as ‘ Fix It‘. Download links are given below.

DriverFinder is another third-party application that can fix Windows devices that are not recognized and are throwing errors on your PC. Simply install DriverFinder software and scan all applications installed on your computer. This useful application finds all the new drivers for your PC. This way, all USB devices including printers will be correctly recognized by your PC, laptop, etc.

Step 9: Other Possible Remedies

In the above steps, I have mentioned all the possible solutions to the “USB device not recognized” problem for Windows 10, 8.1, 7 users. If the problem occurs due to software or operating system issue, then of course, by following the above methods, you can solve the problem of.

If the problem persists, then there will most likely be a hardware problem. Either the USB devices are damaged or the USB port may not be working properly. So, first connect another USB device to this port to make sure there is nothing wrong with the port. Then connect the USB device to another computer and check whether it works or not. If you still get the same error again, then there is a serious problem in the USB drive. You can try a different USB connector.
Connect the USB flash drive to another PC and remove it if the problem occurs as a result of the disk being suddenly ejected.
Turn off your PC and unplug the power cable completely for 5 minutes. This motherboard USB hub reset may help resolve the driver issue. In case you are a laptop user, then remove the battery for at least a few minutes to reset the USB hub on the motherboard.
Update your BIOS and try to fix problems in Windows.

Hopefully this article will help you fix the USB device not recognized error in Windows and now you should be able to work normally with your USB device. Most USB device not recognized errors can be resolved by one of the above solutions. If you have any other solutions, or a USB problem that isn't solved by these tips, please leave a comment!

Greetings to everyone in the next issue, dear users. I think, probably, each of you has seen the error “USB device not recognized” appear when connecting a printer, flash drive or hard drive.

Experience shows that this problem is encountered by users of Windows XP, 7, 8 and 10. In this article I will tell you how to deal with this error and get the device back to work, be it a printer or a simple flash drive. The step-by-step instructions are intended not only for standard USB 2.0 devices, but also for USB 3.0. In general, we can say that the Windows operating system cannot recognize a particular USB device for various reasons. Accordingly, there are also many solutions. I will talk about the main methods for getting the device back into operation.

Instructions for troubleshooting the problem are divided into three separate parts:

First part– check the USB device.

Second part

The third part– solution to the problem with the operation of USB 3.0 in the eight.

USB device not recognized

It is worth saying that the third stage can also help owners of regular USB 2.0 devices. For some reason, it is version 8.1 that constantly conflicts with new devices. In any case, if the mouse, keyboard or any other device is working, then the problem can be solved “software”.

First– check the USB device and solve the problem

You need to start with the simplest steps so as not to waste time. There is a possibility that the error appears due to a damaged device, that is, the problems do not lie in the operation of the operating system. Therefore, I recommend checking whether the printer, mouse, keyboard, hard drive or other “USB gadget” is working properly - this will save time, you will not have to try to start a non-working device.

The easiest way to check is by connecting the device to another computer. The only requirement for this laptop or computer is working USB ports. Don't forget that almost every computer has USB ports located not only in the front, but also in the back - try connecting the device from different sides. If the device does not work on another “machine”, then there is no point in using the methods described above - you need to take the device to a service center or immediately replace it with a new one. Better yet, be sure to read my articles below:

From the above articles, you may find your solution to the problem when the error appears - USB device is not recognized. If you haven’t found it, then we move on.

This method is suitable for those users who cannot check the device on other computers. It is also worth using this method if before this a flash drive or other USB device worked normally. The process consists of two simple steps:

— You inserted the device, the system generated the familiar error “USB device unrecognized.” You need to remove the device and turn off your laptop or computer. Moreover, this must be done completely - remove the plug from the socket and press the power button for about 10 seconds - this must be done in order to completely remove the charges from the computer components and, most importantly, from the motherboard. Now the PC or laptop is completely de-energized.

— We start the computer and again try to connect the USB device with which the error appears. After rebooting the operating system and completely resetting the component, it may work again. If this does not help, then go to the following methods.

There is another method that can solve the problem. You may have too many USB devices connected to your computer at the same time. You need to remove everything except the problematic device. It is recommended to connect this device to the back of the PC (there is no difference for a laptop computer). It worked? Then reconnect the remaining components, after which the error should go away.

IMPORTANT! Some devices that connect to USB ports have an external power source. In this case, you need to connect it and see if it starts from the battery or the outlet. It will be even easier to find out if the device's power supply is working. Let's move on to the second part, in which I will tell you how you can fix the USB device unidentified error.

Second part– restore the device through the task manager and check the drivers.

So, the “USB device unrecognized” error appeared, we made sure that the device on other computers was working properly. This means that the problem lies in the device manager connected to the computer, or more precisely, in the drivers. This method is suitable for all modern versions of the Windows operating system, including Windows 10. I wrote a separate detailed article about the task manager:

What is task manager, nuances and tricks

There are several ways to get to the task manager: in the “Run” menu, enter the command “devmgmt.msc”, and then confirm your action with the “Enter” key. This can also be done using the key combination “Win ​​+ R”. If you are used to going the standard way, then right-click on the “My Computer” icon, go to “Properties”, there you will see the “Device Manager” tab on the right side.

A device that the operating system cannot recognize will most likely be located in the “USB Controllers” or “Other Devices” sections. You can find it by the “Unknown device” label; opposite the problematic component there will be a yellow triangle with an exclamation mark (for Windows 7).

If you see the problematic component in the “Other Devices” section, you can try running an automatic search for drivers. Of course, the system can only do this if your computer is connected to the Internet. You need to click the "Update Drivers" button. If Windows did not find the drivers, then try downloading them yourself. To do this, you need to find out the name of the device, and then find the software for it: go to the manufacturer’s website and go to the “Downloads” section.

If an unknown component is displayed in the “USB Controllers” section, then you should try other solutions to the problem:

Right-click on the problematic device and select the “Properties” tab, here you need to go to the “Driver” tab. Click the “Roll Back” button (this can only be done if it is active; if not, then you should click the “Delete” button). We return to the problematic USB device again, click the “Action” button in the manager, and then click on the “Update the configuration of this device” tab. After this action, it is worth checking whether the device’s unidentified device status has disappeared.

Another option is to go to the properties of all devices called “Generic USB Hub” that are connected to your computer. Go to the “Power Management” section. There is a possibility that the power saving mode will be activated here. You need to uncheck the “Allow turning off a component to save power” checkbox, as shown in the screenshot below.

There is a method that helps with system error 43, which appears when there are problems connecting USB devices. This error usually occurs in Windows 8.1, but sometimes it appears in Windows 10 as well. You need to go back to the devices that were listed in the previous two methods. Now you need to right-click on the problematic component and select “Update drivers” in the context menu.

Now you need to select the software search mode on this computer, then click on the “Select a driver from the list of installed ones” section. You will see a list showing compatible software. Click on it with the left mouse button and move on. After this, the driver will be automatically reinstalled. There is a chance that the device will work normally again. If the “USB device unrecognized” error still appears again, then it’s time to move on to the third part of our article today.

The third part– solution to the problem with the operation of USB 3.0 in eight

Judging by user reviews, Windows 8.1 quite often throws up an error when trying to connect external hard drives or regular drives that run on USB 3.0. The error usually appears on modern laptops.

In this case, the problem must be solved by changing the power settings of the laptop computer. You need to go to the “Control Panel”, there you will find a section called “Power Options”. Click on the scheme that is being used, and then select the “Change advanced power settings” section. In this menu you will see an item responsible for disabling some USB ports. Our first priority is to prohibit temporary shutdowns, as shown in the screenshot below:

In conclusion, I suggest you watch a short review if your USB device is not recognized by the computer.

So, dear users, concluding today’s post “USB device unidentified”, I still hope that my instructions will help you start the problematic device. First of all, you should check the drivers and functionality of the USB component on another computer. That's all and see you all in the next issue.

Sometimes users complain that the computer does not see the mouse. For what reasons does this happen? And how to deal with this kind of situation? The answers to these questions and more will be presented below. Usually, the situation with recognizing PC mice does not bring any significant problems. And there is often no reason to panic either.

Connection methods

First of all, we will try to understand the features of connecting the devices under study. And then we’ll find out why the computer doesn’t see the mouse.

The devices being studied can be connected:

  • via ps/2 connector;
  • via USB cable;
  • via Bluetooth.

Everything is extremely simple and clear. But what if the computer does not recognize the device in question?

Main causes of failures

Computer mouse malfunctions often occur:

  • due to lack of PC power;
  • if the device is connected to the computer incorrectly;
  • subject to incompatibility with the operating system;
  • due to OS failures;
  • if your computer is infected with a virus;
  • due to lack of drivers;
  • if device drivers are outdated;
  • during driver damage;
  • if many peripheral devices are connected to the PC;
  • due to damaged USB ports.

In addition, the computer does not see the wireless mouse (and not only) if the connected device is faulty. The bulk of these problems are quite easy to eliminate.

Correct connection to PC

The first thing you need to do is check how the mouse is connected. It is possible that the user connected it incorrectly to the computer or laptop.

Wired device models do not require any special manipulations - just plug the wire into the appropriate socket (ps/2 or USB). After this, the device will work.

Wireless models require more attention. Usually they need to be connected like this:

  1. Enable Bluetooth on PC.
  2. Plug a special mouse receiver into the USB.
  3. Insert the battery into the device you are studying.
  4. Enable mouse.
  5. Go to Bluetooth devices on your PC and search for new components.
  6. Select the mouse from the list that appears.
  7. Click on the "Connect" button.

Within a few minutes, the mentioned device will work normally on the computer. It is possible that the failure was caused by Bluetooth being turned off. Then you just need to activate it on your computer.

Mechanical damage

Has your computer stopped seeing your mouse? If everything is connected correctly, it is recommended to inspect the wires and adapters. The failure may be caused by mechanical damage. For example, the wires are pinched or the connector is damaged.

Typically, such situations are resolved by replacing faulty parts (repairing) or purchasing a new device. As a rule, if you contact a service center, a broken mouse will be repaired. Only the performance of the device leaves much to be desired.

Battery

Computer doesn't see mouse? What to do in this case?

The next option is only relevant for wireless models. The fact is that they are battery operated. And if the battery runs out of charge, the PC stops recognizing the device.

Accordingly, owners of wireless mice should make sure that the battery is charged. In case of discharge, it is enough to fill the battery with energy. Then performance will be restored.

Port load

Your computer still doesn't see your USB mouse? This is not the worst situation.

The fact is that wired device models may not work due to high load on the connection ports. This is possible if the user has an additional USB connector installed, and there are several devices in it.

You can solve the problem by disabling numerous USB devices. In real life, such situations are rare, but they still occur in practice.

Port damage

If the computer does not see the mouse connected via a wire, you need to carefully inspect the port. It may be damaged. To check, it is recommended to connect any other 100% working device to the USB port. For example, a flash drive.

If the socket is damaged, you can use another one. By connecting a mouse to it, you can avoid problems.

Some users prefer to repair the faulty component along with changing the connection port. It is best to contact a service center for professional help. The master will quickly correct the situation.

Incompatibility

Why doesn't the computer see the mouse? It's hard to believe, but all devices connected to a computer have so-called system requirements. If the PC does not match them, the device will not work. This is a very common occurrence.

In other words, the latest generation of mice will not work on Windows 98 or 2000. It is necessary to check compatibility and minimum requirements when purchasing a peripheral component.

Attention: Recently, Windows 10 owners have been complaining that their computers do not recognize connected mice. Windows 10 does have some compatibility issues. But Microsoft is actively fighting this phenomenon.

The only right decision is to buy a new mouse. Some people prefer to reinstall operating systems to those specified in the requirements for connected devices. What exactly to choose? Everyone decides this for themselves.

Block and power

The following scenario is relevant exclusively for owners of desktop computers. What is it about?

If the computer does not see the mouse, you should make sure that the power supply is powerful enough. It is possible that the PC simply does not have enough power to work normally with the connected devices.

As a rule, replacing the power supply corrects the situation and improves the performance of the devices. It is important to choose a unit that is compatible with the rest of the computer's hardware. Otherwise, further compatibility problems cannot be ruled out.

Viruses

The computer doesn't see the mouse, but it's on? The reasons for this behavior sometimes surprise modern users.

In some cases, the malfunction of the mouse is caused by the presence of spies or viruses in the operating system. Correcting the situation is usually easy. It is enough to scan your computer with an antivirus and remove/“clean” all potentially dangerous objects.

In exceptional cases, a viral infection completely destroys the OS. This leads to the need to reinstall the operating system. After this, the mouse should work as usual.

Drivers and their absence

Why can't the computer see the mouse? Most often, users encounter this problem due to drivers. More precisely, due to their absence.

Driver is a package of programs and utilities necessary for the normal operation of a computer with a connected device. Without it, the device will not pass the recognition stage.

Typically, drivers for mice are installed automatically when you connect a particular model. Sometimes this doesn't happen.

In such circumstances you will need:

  1. Insert the installation disk into the drive and follow the instructions of the installation wizard to complete the initialization.
  2. Go to the manufacturer's website and download drivers from the Internet. After launching the loaded document, you must follow the instructions on the display.

As soon as the drivers are installed on the PC, the mouse will be fully functional. The exception is when the mouse is not fundamentally compatible with the operating system being used.

Update/Corruption

Has your computer stopped seeing your mouse? This may be due to a damaged or outdated driver.

What to do in this situation? You just need to go to the manufacturer’s website, download the drivers from there and install them. This also applies to working with a damaged utility package and outdated software.

Temporarily disabling a port

Sometimes the computer does not see the mouse if the operating system has the function to temporarily disable USB ports enabled. This technique is a means of protection against overload.

To disable this feature, you must:

  1. Open "Control Panel".
  2. Go to the "Power Options" section.
  3. Click on "USB Settings".
  4. Check the "Disable/Prohibited" box next to the "Temporarily disable USB" item.
  5. Save changes.

Now you can reconnect the mouse and see if it works normally. Most likely the problem will go away.

Reboot

Does your computer not see your mouse? What to do in such circumstances?

In some cases, the following will help correct the situation:

  • roll back the system to a date when the mouse worked normally;

That's all. Now it is clear why the computer does not see the mouse. Often the device will not need to be replaced. And even a novice user can cope with these situations.

One of the most common errors when connecting USB devices to a computer is the inability of the operating system to detect the hardware. The user receives a notification if this problem occurs. Regular reconnection often does not bring any results, so you will need to perform additional steps to resolve the problem. Let's look at them in detail.

First, we recommend that owners of Windows OS version 7 carry out manipulations with the device itself and the computer before moving on to radical options, because sometimes such tips help correct the error. You need to do the following:

  1. Connect the equipment to the PC through another free connector. It is best to use the input on the motherboard rather than on the case.
  2. Use a different cable if the device is connected by wires. It often happens that one of the contacts comes loose and because of this, correct functioning with the operating system is impossible.
  3. Disconnect other controllers or storage media connected via USB if they are not needed at the moment.
  4. Reset the component charges. Remove the non-working device from the connector, turn off the PC, disconnect the power supply and hold down the button "Power" for a few seconds, then start your computer. In addition, you can remove and insert RAM dies, preferably into another free slot.

If these manipulations do not bring any results, we advise you to pay attention to the two methods presented below. In them you will find a detailed guide on how to fix device recognition errors in Windows.

Method 1: Rollback or uninstall the driver

In most cases, the problem occurs due to incorrect operation of the drivers. The situation can be corrected in just a few steps, and even an inexperienced user can handle the process, since it does not require additional knowledge or skills. Just follow the following instructions:

Sometimes you need to reconnect the device to start updating the software again. However, almost always the entire process occurs correctly without this action.

Method 2: Change power settings

In Windows, you can configure your power plan to get the most out of your computer's power supply or laptop battery. By default, one parameter is enabled, which may cause the “USB device not recognized” error to occur. Disabling it will help solve the problem. This is done easily:

All that remains is to reconnect the device to the PC and check that it is detected correctly.

Problems with recognizing USB equipment in the Windows 7 operating system occur quite often. However, as you can understand from our article, it can be solved quite easily, it is only important to choose the right method and follow it.
