Device Descriptor Request Failed Fix (2022)

There could be many reasons that might lead to the device descriptor request failed error on Windows 10.

Irrespective of what reason causes this error on Windows 10, you can easily fix it by applying the following methods.

Here are all possible ways to fix the device descriptor request failed error:

Solution 1: Check For Hardware Issues

Whenever you encounter the device descriptor request failed error on Windows 10, the first and foremost thing you should do is check for Hardware issues.

There are chances that you might be having this USB error due to your hardware.

To check whether your Hardware or Operating System (OS) is at fault, you can use the following methods:

  • Plug Your USB into a Different USB Port — Try to plug your USB into a different USB port and if it works, then the USB port you were using earlier is likely damaged.
  • Plug Your USB Into A Different PC — Try to plug your USB into a new PC and if it works on it, it is your system that causes the error, not the USB.

Solution 2: Plug-Out Your Power Supply

Note: This solution is only recommended for people using a portable device like Laptop.

There are users who suggested temporarily unplugging your power supply and then connecting the problematic USB to your Laptop to fix the Unknown USB Device error.

All you need to do is unplug all cables from your Laptop until your Laptop is running on its integral battery.

When it happens, plug in the USB device and check if your Laptop is recognizing it or not.

If you continue to encounter the same device descriptor request failed error, it means the power supply you are using is at fault.

If your Laptop recognizes a USB port, replacing your charger is highly recommended.

Solution 3: Uninstall the USB Driver

The third method that we have for you needs you to uninstall the USB Driver in Device Manager.

Do you know how to remove or uninstall the USB Driver in Device Manager?

If your answer is NO then follow the steps mentioned below:
