Struggling with the “Unknown USB Device Descriptor Request Failed” error? Let’s find a solution together.
Troubleshooting Hardware and Power Supply Issues
If you are facing the “Unknown USB Device Descriptor Request Failed” error on your Windows 10 laptop, it could be due to hardware or power supply issues. To troubleshoot this problem, follow these steps:
First, try connecting the USB device to a different port on your computer. Sometimes, the issue could be with the USB port itself.
If that doesn’t work, restart your computer to see if the error persists. A simple reboot can sometimes fix hardware-related problems.
Next, check the USB device on another computer to see if it is recognized. If it works on another computer, the issue may be with your laptop.
You can also try updating the USB device driver in Device Manager. Right-click on the USB device, select “Update driver,” and follow the on-screen instructions.

If none of these steps work, you may need to check the power supply unit of your computer. Make sure it is providing enough power to all connected devices.
