    Try this:
    > Shudown computer
    > Unplug computer power cord. If a laptop remove battery too
    > Unplug all USB and other non-essential devices

    Let is sit overnight

    Now plug in, power up computer in the morning. When you reconnect your USB devices, if they have their own AC adapter
    > USB device should be turned off
    > plug USB device into AC plug
    > plug device into USB port
    > now turn USB device ON

    is it recognized?
