It happens that when you turn on the computer, you suddenly notice that the mouse does not respond to your movements. This can happen with both a wired USB and a wireless mouse. Usually, the reasons for this are the same type of cases and are already known to many specialists. Therefore, we will consider all the most popular reasons why the computer does not see the mouse and we will give several solutions in the article that should definitely help you.

First of all, your task is to determine whether your reasons for a non-working mouse are primitive.

Ways to solve the problem with a USB mouse

If the problem occurs with a mouse that is connected via a USB port and the computer does not see it when it is turned on:

• Disconnect the mouse USB connector from the computer panel and turn off the computer. Disconnect it from the mains and press the power button on the computer for a few seconds - this way you will completely clear the computer modules from charges, first of all, the motherboard.
• Now turn on the computer and connect the mouse after Windows startup. The mouse should work.

Now let's fix the problem with the USB mouse using. This method is appropriate when the system does not recognize such a device in the device manager of your PC. To open Device Manager, click on the "My Computer" icon right click mouse and select the appropriate item or via command line WIN + R and type the command "Devmgmt.msc" and press Enter.

You will find the device in the body of the list, it will look like "USB controllers" or "Other devices" ("Unknown device"). If it is in your list looks like an unidentified device, then you need to right-click on it and select "Update Driver". In this case, the system automatically finds required drivers and installs them without your intervention. After this installation, you can use a working mouse.

If there is an exclamation mark next to our mouse in the task manager:

Physical breakdowns due to which the computer does not see the mouse

With careless use, even the USB connector can become unusable. Check the pins on the port and in the mouse connector, they may be damaged, bent, worn out. Although the USB connector is very durable, it could still break with active use, and the contacts could also loosen. In this case, you need to contact the service USB replacements ports on motherboard or buy a new one.

The mouse cable can also suffer from all sorts of damage that leads to a break in the wires inside the cable. There are cases when they are gnawed by domestic animals. In this case, the system will notify you with a message - "Unable to connect to the USB port" or. The USB cable has 5 cores, which are not so easy to reconnect together. This is probably the easiest place to buy. new mouse. If the model is expensive, it can be saved in the service.

In addition to the wire, breakdowns can also occur in the mouse body itself.

The main faults inside the case:

• The lens surface is dirty, scratched.
• Buttons don't work. The arrow runs around the monitor, but click commands are not executed.
• Faulty main board, reader, photocells, etc.
• The wheel controller is defective. In this case, there is no way to scroll the pages up and down.
• Unreliable front USB ports. When several ports are connected to the board of one microcontroller. It happens that inexperienced users connect several 4G modems and printers to such ports at the same time - if a failure does not happen, then it will definitely happen. Modems will often lose cellular network and periodically terminate the connection. The same will happen with the printer, it will slow down in every possible way, stop without printing the document to the end. The USB mouse may not be recognized by the system. As you may have guessed, you need to distribute the equipment across all USB ports of the computer, including on the rear panel.

On wireless mice:

USB 3.0 laptop does not see the mouse

Laptops running the 8.1 operating system often encounter the “USB device not recognized” error. To prevent this problem? You need to change your laptop's power plan.

Mouse issues across devices and versions of Windows

After reinstalled Windows systems Chipset driver incompatibility may cause the mouse to malfunction. Each operating system includes touch, mouse, touchpad drivers, except for MS-DOS. A common cause of mouse failure is a non-working USB driver, component - "Serial Bus Controller" and "Root Hub". You need to find on the net the version of the chipset that will fit the version of Windows OS that is installed on your computer. this moment. Although for 8.1/10 versions, the main drivers are already provided as system components, they do not need to be installed separately.

ACER netbooks, which are provided with Windows 7 by the manufacturer, when installing versions above, a problem appeared - the mouse did not work. The problem was in the hardware of the netbook - the Windows 7 chipset drivers did not fit and the following problems arose: the wireless network connection, the sensor did not work, the mouse did not work (the pointer was in one place). The problem was solved by removing the drivers and restarting the operating system. Devices and equipment worked normally again.

Connecting via a USB port is one of the most popular ways to quickly transfer data today. You can also simply charge the connected device using the USB connection. Such functions are in demand, so nowadays 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 are also connected to the PC.

Naturally, with such a variety of devices, some errors will certainly occur. Basically, they are divided into two categories: recognition errors, which this article will be about, and formatting errors, about the solution of which you can read.

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

"USB device not recognized" - what to do in Windows 7, 8

Any computer can suddenly throw out such a nasty surprise with any device: USB drives, smartphones, tablets, computer mice, keyboards, accessories, printers, scanners ... With everything that can be somehow legalized via USB, such a problem may arise, but for almost any device such an error is solved in the same way.

The first thing to do when Windows doesn't recognize a device is to check if it's working. 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 except going to the store for a new analogue.
Also try connecting the device to a different USB port, temporarily disconnecting unnecessary equipment. If nothing worked, then go 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 so happened that it got into the "Unknown devices" tab, right-click on it and update the drivers. In the event that the gadget is 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 selecting your USB device.

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

The computer does not see the flash drive via USB

First, your Personal Computer most often it does not detect a flash drive due to the fact that it is faulty. To check this, insert the USB flash drive into another device. If it does not work and is not dumb, then feel free to buy another flash card.
Second, check the connector for dirt. Naturally, if banal dirt gets into the flash drive connector, it will not work correctly.
Thirdly, try inserting the USB flash drive into another slot on the computer (usually there are several).
Next, try formatting your flash drive for the computer's file system. You can see which file system on your PC by going to properties local disk. Now you just need to specify when formatting which file system you need.

Phone 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 another way. You connect your smartphone via a special cable, but nothing happens, and Windows does not react in any way to a new connected device and simply charges its battery.
But why does the computer not see the phone via USB on the android, it only charges and nothing else? How to solve it?

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 must either upgrade to a newer OS, or download the Media Transfer Protocol program from the official Microsoft website, install it and restart your PC - everything should work.

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

3. Try changing the USB cable. Faults in the cable 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 does not want to work correctly, then the problem is either in it or in the USB cable. If everything worked, then the whole problem is in the computer options - go to the next step.

6. Try plugging another device into your computer (a flash drive, for example). If an error also occurs with other flash drives, then go to the "Control Panel" and select the "Troubleshooting" item. In it, click on "Device Settings". An automatic setup will take place.

7. If the computer still does not see the smartphone, then only updating the drivers remains.

Note: the newest phones are now set by default not to transfer data, but to charge. To check which type USB connections is used, use the simple instructions from the screenshots, which is located below.

Problem connecting USB stick to tablet

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

The main reason for this error is different standard file systems. Then you need to format the flash drive in FAT32 (modern tablets are sharpened for such a system) through a computer.
If this does not help, then you need to get root access to the device and boot from Google Play the StickMount application, through which you can virtually mount a USB drive after inserting it into the tablet.
If none of the above methods helped, then think about repairing the tablet.

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 a flash drive/USB drive, you may receive the following error message: “USB device not recognized”. In it Windows time, shows a message that the USB device is not recognized as a pop-up notification in the panel area Windows tasks. Windows shows an error message due to an unknown problem with the Windows operating system, which results in USB not being recognized and an error. What would you do in this case?

Error says:

In Windows 8, 8.1 and Windows 10 -
The latest USB device is not properly connected to this computer and Windows cannot recognize it.

or, in 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 with this issue, click this message.

When an error occurs, Windows cannot show the USB mass storage device under 'My Computer' in the explorer area, and if you can take a look at Device Manager in Windows, then you will find a yellow triangular alert icon next to 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 such an 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 OS version (it can 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, inserting a USB flash drive or external USB disk to your PC. In fact, there is no exact and specific reason for getting this error message. So, we have to identify the problem of such an 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 to those that cause the device not to be recognized by the system. Most of the time, users using USB and Windows virtual operating systems get an error message, but quite a few cases I have had myself when I plugged a USB flash drive directly into the My Computer window.

How to resolve and fix ‘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 external drive its not recognition so you can get the same windows errors any time you plug in a USB device to a Windows USB port.

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

After you receive an error notification, simply remove the USB device and insert it again. Try this same method two or three times. If you're lucky, you might be able to get rid of the Windows error that's preventing you from accessing a particular USB device. If this tool works for you, then it could be a problem loading the device driver in Windows at the time of introduction. external USB to your PC.

Step 2: Disconnect the USB drive and re-insert it into a different USB port

Try a different USB port while you keep getting the error message. There may be a problem with the USB port. The USB port can be mischievous or have mechanical problems over time. Therefore, try to use a separate USB port to solve the problem, if this helps, then this is probably a problem with the USB port. Replace the USB port immediately so that you don't get any more errors in the near future for 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 fails to load at startup, your computer may be behaving badly, and as a result, a “USB device not recognized” error may occur.

Step 4: Troubleshooting Windows Device Manager and Usb Drivers

This step is the most important. Majority Windows users who receive such an error can fix it using the Windows Device Manager. In Device Manager, you can find all connected devices on your PC, including processors, printers, hard drives(internal and external), etc. So, how to find and fix the problem of recognizing a 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 Device Manager in a Windows window.

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

A USB device that is not recognized by Windows is marked as 'Unknown device'. You can update drivers in Windows right click in context menu. You need to select an 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 let it work around this error. But, if the message is still there, it is better to uninstall the device driver and reinstall latest version Internet drivers.

Now select the USB Root Hub - Properties and under the 'Power Management' tab you will find the option "Allow the device to turn off to save power". Uncheck the box and see if that helps or not.

Step 5Disable USB - Selectively Pause Setup

There are various power options in your computer's control panel. Select "change plan options" of your running plans and click on the option "change Extra options nutrition". Now scroll down to USB Settings >> USB Selective Suspend >> Install and force it to turn off. Notebook users should select the battery option and then do disable.

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

Many Windows 10 PC users may encounter the same problem. In addition, when connecting a device using USB cable, the device remains disabled. When you connect a USB device to a PC with a USB cable, the device is charged by the PC. In this case, for Windows 10 users, when you plug the device into the USB port, the device gets a charge, but the PC does not display the device in File Explorer. Sometimes, users get “USB Not Recognized” error message. The troubleshooting procedure is described below.

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

Now open the 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 get the error fixed message.

Step 7Remove Existing Hidden Devices

Windows Device Manager does not show all devices in the list. It only shows the devices connected to the PC. Devices that were previously installed and are 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, then it will not be displayed in the Device Manager list. However, some hidden devices can 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 command prompt as administrator and run the following commands:

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

After Device Manager loads successfully, in the top navigation select View >> Show Hidden Devices.

Now, find and manually define the list of unused drivers and remove them. You can check unknown devices, USB controllers, etc.

New devices can now work just fine after uninstalling old devices and drivers. Thus, we hope you 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 the device still does not work for you, you should try the 'fix' applications from Microsoft. There is also another useful tool from Microsoft to do this job. The tool known as ‘ Fix It‘. Download links are below.

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 possible solutions“USB device not recognized” problems for Windows 10, 8.1, 7 users. If the problem occurs due to software or a problem with operating system, then, of course, following the methods described above, you can solve the problem.

If the problem persists, then there will certainly be hardware problems. Either the USB devices are damaged or USB port may not work correctly. So, first plug another USB device into this port to make sure everything is ok with the port. Then plug the USB device into another computer and check if 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 a sudden drive ejection.
Turn off the PC and unplug the power cable completely for 5 minutes. This motherboard USB hub reset can help fix the driver issue. If you are a laptop user, remove the battery for at least a few minutes to reset the USB hub on the motherboard.

I hope this article will help you fix the error in Windows device USB is not recognized and you should now be working fine with your USB device. Most errors - USB device not recognized - can be resolved by one of the above solutions. If you have any other solutions, or a USB problem that these tips don't solve, please leave a comment!

Doesn't work properly" on its own. They know their computer down to the smallest detail, so there are no questions about how to fix this or that error. But for inexperienced users in this matter, it is much more difficult. For some, even advice from the Internet does not help, because there is too little knowledge and experience.

Problem

But that's not a problem. Any basic PC error can be resolved quickly. To do this, you need to carefully study the instructions and follow step-by-step advice from experts.

Today's problem is when one of them doesn't work properly. Most often, you will notice this text in the lower right corner of the desktop. Sometimes a special window appears with a notification about this problem.

Prerequisites

Most often, the error occurs when connecting any device via USB. This and regular flash drive, and a telephone, and a printer, etc. The problem occurs both at an early Windows versions 7, and on the later - "Ten". However, your USB may be version 2.0 or 2.0. In general, the essence of the issue does not change from this.

The reasons

An error accompanied by a USB connection can be caused by a number of reasons. Indeed, there are a lot of them. And they are not always typical. It happens that the fault lies directly and completely with the user, who miraculously removed the drivers or confused the system. There are also flaws on the part of the manufacturers of these devices. Poor quality Chinese flash drives are especially prone to this problem.

Trust but verify

So, you saw a similar error on your screen. In order to avoid unnecessary nerves and wasting a lot of time, it is better to immediately check the device that you connect to the port. As mentioned earlier, not all manufacturers are so conscientious. Many people create a product just to sell. This results in system errors.

If you bought a new mouse, keyboard or flash drive, immediately check that it is working properly before sinning on USB interface. To do this, you can use two methods:

1. If you have a second PC or laptop, just connect your new device to it. If everything is fine on another system, then most likely the problem is in the computer.
2. Take a working device (an old mouse, a second flash drive, etc.) and insert it into the same port. If the same notification appears, then the problem is really in the connector.

There are a couple of hidden ways. They do not always give a clear picture of what is happening, but just in case, you can try them out. So, we take the device that gives an error, disconnect it from the PC and turn off the system along with the plug in the outlet. Now you need to hold down the start button on the computer so that the remnants electric charges left the motherboard.

Now turn on the PC and connect the USB device when the system boots up completely. The option is not the best, but sometimes after it everything really starts to work.

And for those who finally want to make sure that the port is malfunctioning, you can simply turn off all the USB that are on the interface panel. It happens that port overload can give a similar error. If you turn off equipment that is not currently needed, install the USB flash drive in the back panel.

Software methods

Sometimes the problem “One of the connected USB devices is not working properly” cannot be fixed by reshuffling alone. We'll have to dig inside the system. If all the previous methods did not give you a result, let's try to update the "firewood".

To do this, we are looking for "Device Manager". We do it through the command line: hold down Win + R on the keyboard and enter devmgmt.msc in the field. You can go to "My Computer", right-click anywhere in the window and select "Properties". A window with PC parameters will open in front of us, and in the left column you will find the desired section.

So, in the "Device Manager" select the line "USB Controllers", everything is shown here USB equipment connected to the system. There will be a line "Other devices", it is in it that our unknown device will be located. Click on its name and try "Update Drivers". We are waiting for the system itself to download the necessary files via the Internet, and, perhaps, the flash drive will “come to its senses” and work.

Exclamation point

It may be that next to this " unknown device» is a yellow exclamation mark. In this case, we try to roll back the drivers. Click on it and go to Properties. Here you need to find a tab with "firewood" and the "Rollback" button. Perhaps it will be unavailable to you, highlighted in gray. Then select "Delete".

Now you need to return to the "Device Manager" window and select the "Action" section from the top, and update the hardware configuration in it. These steps may fix your issue.

The exclamation point may appear for another reason. To do this, you need to go to the properties of the equipment that has acquired names such as Generic USB Hub, USB Root Controller and USB Root Hub. In the window that appears, select "Power Management" and uncheck the first line. This will prevent the equipment from turning off to save electricity.

Common Mistakes and Solutions

As mentioned earlier, the error “One of the connected USB devices is not working properly” is individual and depends on many factors. We have covered the most common causes above. And now let's briefly try to describe what kind of malfunctions other users encountered.

Often this error occurs when connecting a printer. Usually caused incorrect installation"firewood". Therefore, you can simply remove them and carefully reinstall them again.

Many problems arise from mechanical damage. Suppose a cable with a micro-USB connector on one side and USB on the other can be broken or crushed in the middle. It also significantly affects the performance and synchronization of it with the PC.

Another interesting problem, which is now becoming less and less common, can be incompatibility. Some devices do not support 2.0 or newer 3.0. Then it happens that by connecting through USB phone or any other device, you will see this message again. In general, if such a problem has arisen, then it is better to think about changing the motherboard, since the interface standard will continue to change, and there will be even more problems.

Laptop problems

In this case, we are facing USB 3.0 connectivity issues. Due to the imperfection of this revision of the interface, users have to get out different ways. A solution has been found. The laptop needed to adjust the power plan.

To do this, you could go to standard settings this parameter or in proprietary software, which is provided by some laptop manufacturers. In Windows, select the power plan that is currently in use, then go to advanced settings. And already according to the familiar scheme, we prohibit disabling ports to save energy.

conclusions

If suddenly you cannot connect a phone via USB, an external HDD, flash drive and other devices, you don’t need to get upset right away. First, the breakdown of one port out of ten in the system is a common thing. Trying to just use a different connector is as easy as shelling pears. Secondly, even if in program plan If it doesn't work, you can try reinstalling Windows.

Of course, reinstalling the OS is not a panacea for all problems and the process is quite difficult, especially for those who have never encountered it. However, even he can help you.

It is possible that your micro-USB connector is not working due to a real controller failure. It cannot be replaced on the motherboard. This is either buying a new motherboard, or, alternatively, purchasing an external controller with a PCI interface.
