Most computers have more than one USB port , so a good way to rule out a single broken port is to want to unplug your USB device and try it in a different port. If your device starts working when plugged into a different port, then the first port probably has a physical problem that needs to be fixed if you want to ever rely on it again. USB cable failures are more common than USB port failures, so make sure to swap in a different cable if you have one handy.

If your device suddenly starts working, then you know that the problem was a broken wire inside the other cable. If you have another computer or laptop handy, then try plugging your USB device into it.
