Are you encountering the frustrating “Unknown USB Device: Device Descriptor Request Failed” error on your Windows computer? This error message often pops up when you plug in a USB device, preventing you from using it properly. However, fear not! In this guide, we’ll explore ten effective methods to troubleshoot and fix this issue, so you can get your USB devices working again without a hitch.
1. Restart Your Computer
Sometimes, a simple restart can resolve many technical glitches. Restart your computer and try connecting the USB device again to see if the error persists.
2. Try Another USB Port
The problem might be with the USB port itself. Plug the USB device into a different port on your computer and check if it’s recognized without any errors.
3. Update USB Drivers
Outdated or corrupt USB drivers can cause compatibility issues and trigger the “Device Descriptor Request Failed” error. Update your USB drivers through Device Manager or download the latest drivers from the manufacturer’s website.
4. Uninstall USB Drivers
If updating the drivers doesn’t work, try uninstalling them and then reinstalling them. Right-click on the USB device in Device Manager, select “Uninstall device,” and then restart your computer to reinstall the drivers automatically.
5. Disable USB Selective Suspend Setting
USB Selective Suspend is a power-saving feature that can sometimes interfere with USB device detection. Disable this feature in your power plan settings to see if it resolves the error. Navigate to Power Options > Change plan settings > Change advanced power settings > USB settings > USB selective suspend setting.
6. Reset USB Root Hub
Resetting the USB Root Hub can often fix connectivity issues with USB devices. Open Device Manager, expand the “Universal Serial Bus controllers” section, right-click on each USB Root Hub, and select “Uninstall device.” Restart your computer to reinstall the USB Root Hubs automatically.
7. Update BIOS/UEFI Firmware
Outdated BIOS/UEFI firmware can cause various hardware-related issues, including USB device errors. Check your computer manufacturer’s website for firmware updates and install them according to the provided instructions.
8. Disable USB Legacy Support
Some computers have USB Legacy Support enabled in the BIOS/UEFI settings, which can cause compatibility issues with modern USB devices. Access your BIOS/UEFI settings during startup (usually by pressing a specific key like F2 or Del), navigate to the USB configuration section, and disable USB Legacy Support.
9. Check USB Device for Hardware Issues
Ensure that the USB device itself isn’t faulty by testing it on another computer. If the device works on another computer without any issues, the problem likely lies with your computer’s USB ports or drivers.
10. Perform System Restore
If the error started occurring recently after a system change or update, performing a system restore to a previous point in time can help revert your system to a stable state. Search for “System Restore” in the Start menu, follow the on-screen instructions, and choose a restore point before the error occurred.
