Hvernig á að laga USB-tæki sem ekki er þekkt í Windows 11/10/8/7

“USB device not recognized: The last USB device you connected to this computer malfunctioned and Windows does not recognize it.”

This is a common problem that often occurs in Windows 11/10/8/7 when you plug in a mouse, keyboard, printer, camera, phone, and other USB devices. When Windows stop recognizing an external USB drive that is plugged into the computer, this means that you are unable to open the device or access the files saved in it. There are many reasons why your Windows computer fails to detect the connected USB device, and the solutions to the problem are also varied.

In this article, we’ll explain the possible causes of USB devices not recognizing the error and offer you 7 of the most effective solutions to fix a USB device that is not recognized in Windows 11/10/8/7/XP/Vista.

Possible Causes of USB Device Not Recognized Error

As we mentioned before, there can be varied reasons why your Windows 10/8/7 computer is unable to detect the connected USB device. These include the following:

  • The USB drive plugged into your Windows computer may be unstable or corrupt.
  • Windows system could also be outdated and requires an update particularly for components that deal with USB drives or other external hard drives.
  • Windows could also be missing some important updates for other hardware and software components.
  • The USB controllers on the computer may be unstable or corrupt.
  • The PC’s motherboard drivers may be outdated and need to be updated.
  • It is also possible that the external drive has entered selective suspension.
  • The USB port might be damaged or faulty.

To fix the USB device not recognized error, the following are just some of the solutions you can try:

Tip 1: Unplug Computer

The first thing you should do when faced with an unrecognized USB drive is to unplug the computer. And here we don’t mean using the “Power” feature to turn off the computer, but unplugging it completely from the power source. Rather than simply reboot the computer, this action will reboot the motherboard which contains all the hardware components including the USB ports. Doing this will fix the insufficient supply to the external drive. So when you plug in the computer again, your USB device should be detected. If not, try the next solution.

Tip 2: Change USB Cable or USB Port

You should also check whether the USB ports on your computer are working correctly. If the ports are not functioning as they should, Windows will not be able to detect the USB device. If you have been using one port, change to another. If you don’t have multiple ports on the computer, consider buying a USB hub. If the device was connected to the computer via a USB hub, consider connecting it to the computer directly.

Tip 3: Fix USB Root Hub

Follow these simple steps to try and fix the USB Root Hub:

  1. Launch Device Manager on your computer and then locate the “Universal Serial Bus” controllers and click on it to expand.
  2. Locate the option of “USB Root Hub”, right-click on it, and then select “Properties”.
  3. Tap on the “Power Management” tab and uncheck the “Allow the computer to turn off this device to save power” option. Then click “OK” to apply the changes.

Tip 6: Update USB Device Driver

Since this problem is often caused by outdated drives, you may also be able to fix it by updating the USB driver on your computer. Here’s how to do that:

  1. Open Device Manager. You may be able to find it by simply using the search function or by hitting the “Windows + R” key on your keyboard. In the run box that appears, type in “devmgmt.msc” and hit “Enter”.
  2. Once Device Manager is open, expand “Universal Serial Bus Controllers” and you will see a drive marked “Generic USB Hub”. Right-click on it and choose “Properties”.
  3. Click on “Update Driver” and then choose either “Search Automatically for Updated Driver software” or “Browse my computer for driver software” and Windows will install the drivers for you.

  1. Open Device Manager as we did in the previous section.
  2. Find and expand “Universal Serial Bus Controllers” again. Right-click on the USB drivers and select “Uninstall”.
  3. Do this for all USB drivers and then restart the computer and the drivers should be automatically reinstalled on your system.
