    Start troubleshooting process by unplugging all USB devices, doesn't
    matter, if it's empty USB extension cable, external USB hub, or USB
    thumb drive.
    If you did that already and don't have USB-anything plugged in and
    still have the same issue, then this is a hardware problem, not a
    software problem.
    If you unplugged everything and can't reproduce the issue anymore,
    then you have faulty USB device, which should be tested one by one,
    to determine which one is the culprit.
    
    There is one additional thing, if your "PC" is a laptop, then it is
    possible there is an internal device inside that uses USB bus to
    function, e.g. WiFi adapter, WWAN adapter, etc.
    In that case you need to open laptop to remove these devices.
    If your laptop is HP or Lenovo brand, you should look for publicly
    available Disassembly and Maintenance Manuals for your model on
    manufacturer's official website.
