Power surge on the USB port
The following methods have proven to be sufficient to fix the Power surge on the USB port error on Windows 10:
Run the Hardware & USB Troubleshooter.
Reinstall, Uninstall or Rollback the USB drivers.
Use a USB Hub
Run OEM diagnostics.
1] Run the Hardware & USB Troubleshooters

2] Reinstall, Uninstall or Rollback the USB drivers
You need to either update or rollback the driver. If you just updated any driver, and the issue started after that you need to rollback the driver. If you did not, then maybe updating this device driver to its latest version will help.
The drivers you need to work with are the ones under the option of Universal Serial Bus Controllers.
You can also uninstall the driver and then search the web or use Windows Updates & download the latest version of your driver and install it. Check if that fixes your issues.
3] Use a USB HUB
If the error occurs with a specific device, then it is possible that the device is requiring more voltage.

4] Run OEM Diagnostics
