    Check the Device Manager (Windows)

    There are two things you can do with the device manager in Windows to get USB ports working again. ... Right-click on the name of your computer, and then left-click on scan for hardware changes. Wait for the scan to complete and then check your USB device to see if it works.

    Some USB ports do not offer power.  You need a powered USB to charge a phone.
