- Expand Universal Serial Bus controllers
- Right-click USB Root Hub
- Select Properties
- Open Power Management
- Uncheck:
✅ Allow the computer to turn off this device
Repeat for all USB Root Hub entries.
Restart your PC.
Method 6: Perform a Full Power Reset (Hidden Hardware Fix)
This method works surprisingly well.

Save and restart.
Method 9: Fix Corrupted System Files

sfc /scannow
Wait until scanning finishes.
Then run:

Restart your PC.
Method 10: Check Hardware Failure (Last Step)
