The error message "Power surge on the USB port" on a Windows computer usually indicates that a USB device requires more power than the USB port can put out. This wikiHow article teaches you how to troubleshoot the "Power surge on a USB port" message in Windows.
Power Surge on the USB Port: What It Means
This error indicates a USB device connected to your PC needs more power than it can get from the port. Check to see if the problem occurs on other USB ports and try a different cable. Check for updates, and try a powered USB hub if the error persists.
Steps

Check all USB devices connected to your computer. Disconnect all USB devices connected to your computer, then plug each back in one at a time. See if the error message shows again when you connect a USB device. If you see "Power Surge on the USB port," you'll know which port and/or device to troubleshoot.

The USB cable may be shorting out. Examine the USB cable to see if there are any exposed wires. Check the inside of the USB connector to see if there is any dirt, debris, or loose prongs in the connector. Try using a different USB cable. If the device works using a different USB cable, the problem is the cable.
