>Description:
        If USB device (like phone or UPS) was connected before system boot it
        comes into
        uhub0: device problem, disabling port 1
        at startup
        It would never work until reconnected to another USB port. This doesn't
        concern keyboards and mouses.
        Noted on many different boxes.
>How-To-Repeat:
        Just use your UPS into USB port and boot system. Seems RC3 has same 
        behaviour.
>Fix:
        Only reconnect as a workaround.
