:Hmm. So I'm assuming this error message isn't really an

    It's not an issue for USB, but it is an actual error... well, more like
    a warning.  USB is generating an interrupt which is not being handled
    by the interrupt service routine, or which is being generated before
    USB is able to install its service routine, Resulting in an interrupt
    spam.  If the livelock code didn't exist the system would lock up at
    that point in the boot.  But it does exist so the system survives, and
    the livelock goes away after the driver has been completely configured.

    I would love it if someone could track down the cause of the interrupt
    spam.
