Windows has a default setting which turns off USB controllers to save power when they are not being used. It is turned on automatically when the need arises.

- Finally, un-tick the box next to ‘Allow the computer to turn off this device to save power’. Proceed by clicking on OK.
- Repeat the steps from step 3 for every USB Root Hub device you have on your list under Universal Serial Bus controllers.
Method 4: Update your USB drivers
Your current USB driver may not be compatible with the updated Windows 10. Updating your USB driver to the latest version will probably fix this. After you have updated it, check to see if the problem has been resolved.
Method 5: Replace your USB ports
If your problem still persists even after trying all of the above methods then your USB ports might be damaged. For confirmation, you should get your PC examined at the repair shop. If they are damaged, then you can get them replaced at a very reasonable price.
