USB Device not recognized


I have a weird issue for almost 1 month and I really cannot find a solution to fix this problem.

I have a popup in the tray that a USB device has malfunctioned etc. (you can see the whole message on the pictures below)

I tried everything (I think),

-uninstalled the device from device manager, it comes back...

-removed all usb devices of my pc, it comes back..

-pull off the power supply and let the computer for some time, it comes back...

I am out of ideas, can anyone help?


Hi Alex,

Thank you for posting your query on Microsoft Community.

I appreciate your troubleshooting steps.

As per the description, I understand that you are getting a pop up saying USB device not recognized.

This might have occurred due to some third party application conflicts.

I would like to know some information.

  1. What is the make and model of your computer?
  2. Have you installed any antivirus security software program on your computer?

Try the methods.

Method 1:

I would first suggest you to remove all the external devices connected to your computer and try the steps given below.

Note: Ghost devices are the previously installed devices which are not connected but the drivers for that device is still present in the computer and sometimes shows in the devices list.

To get rid of unwanted drivers, devices, or services, use the following steps:

  1. Open the Start menu.
  2. Swipe to the upper right corner to bring charm bar.
  3. Type cmd in search box.
  4. Select cmd from the displayed list, right click and Open as administrator.
  5. At the command prompt, type in set devmgr_show_nonpresent_devices=1 and press Enter.
  6. (Note that nothing seems to happen. This is expected. You are actually setting an environment variable which is going to help you to see hidden devices.)
  7. On the next command prompt line, type devmgmt.msc and press Enter. This will launch the Windows Device Manager Console.
  8. In the Device Manager Console, from the View menu, select Show Hidden Devices.

As you expand the different drivers and devices in the device manager, you will see not only the items that Windows currently detects as installed on your PC; but you will also see drivers, devices, and services which have been loaded in the past but were not uninstalled or are not currently started. You can find your offending device, right-click, and choose uninstall to remove it from the system completely.

Note that ghost devices, drivers, and services are “grayed” out, but that does not necessarily mean that you should delete all of them. Only remove items you know you do not need. Be careful that you do not change too many devices.

Once you have removed the ghost drivers completely from the system, try to reinstall the drivers for the Webcam and check if it helps.

Method 2:

If the issues still persists, I suggest you to perform clean boot and check, using this Microsoft Article because may be a third party application is causing this issue.

NOTE: A clean boot is performed to start Windows by using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program or an update or when you run a program in Windows. You may also troubleshoot or determine what conflict is causing the problem by performing a clean boot. You must log on to the computer as an administrator to be able to perform a clean boot. Your computer may temporarily lose some functionality when you perform a clean boot. When you start the computer normally, the functionality returns. However, you may receive the original error message, or experience the original behavior if the problem still exists. If the computer is connected to a network, network policy settings may prevent you from following these steps.

Once you perform clean boot do refer to the section “How to reset the computer to start normally after clean boot troubleshooting” to boot the computer in normal mode.


Hope this helps. Please let us know the results. We will be glad to assist you further.
