The "Device Descriptor Request Failed" error typically occurs when Windows cannot identify a USB device connected to your computer. This issue can arise due to various reasons such as driver problems, hardware issues, or even power management settings. Here’s how you can fix it:
1. Replug the USB Device
- Disconnect the USB device and reconnect it after a few seconds.
- Try connecting the device to a different USB port.
2. Restart Your Computer
- Sometimes a simple restart can resolve the issue. Restart your computer and check if the device is recognized.
3. Update or Reinstall USB Drivers
- Device Manager: Open Device Manager by pressing
Win + Xand selecting "Device Manager." - Locate "Universal Serial Bus controllers."
- Find the USB device with a yellow warning icon or labeled "Unknown USB Device (Device Descriptor Request Failed)."
- Right-click on it and select "Update driver" or "Uninstall device."
- If uninstalled, restart your computer, and Windows will automatically reinstall the drivers.
4. Disable Fast Startup
- Open Control Panel and go to "Power Options."
- Click on "Choose what the power buttons do."
- Click on "Change settings that are currently unavailable."
- Uncheck "Turn on fast startup" and click "Save changes."
- Restart your computer and check the device again.
5. Check Power Management Settings
- Open Device Manager.
- Expand the "Universal Serial Bus controllers."
- Right-click on the "USB Root Hub" and select "Properties."
- Go to the "Power Management" tab.
- Uncheck "Allow the computer to turn off this device to save power" and click "OK."
- Repeat this for all USB Root Hubs.
6. Use USB 2.0 Ports
- If you’re using a USB 3.0 port, try connecting the device to a USB 2.0 port instead, as some older devices may not be fully compatible with USB 3.0.
7. Try the Device on Another Computer
- To rule out hardware failure, try connecting the USB device to another computer. If it works, the issue is likely with your original computer's settings or USB ports.
8. Check for Hardware Issues
- If none of the above solutions work, the USB device or the USB port might be faulty. Try using a different USB device to see if the error persists.
9. Run the Hardware and Devices Troubleshooter
- Type "Troubleshoot" in the Windows search bar and select "Troubleshoot settings."
- Click on "Additional troubleshooters."
- Find and run the "Hardware and Devices" troubleshooter.
If the issue persists after trying these steps, the USB device may be damaged and require replacement.
