Logic 9 Unknown USB Audio Device

    Logic Pro 9.
    I keep getting the warning message, "Unknown USB Audio Device detected" and I'm asked if I want to use it. Answering either Yes or No seems to make no difference. I keep getting the warning everytime Logic does a rescan of the attached devices.

    I have no idea what Unknown USB Audio Device it's detecting. The System Profiler doesn't report any such thing, and everything that is connected Logic seems to know about. The Apple MIDI Setup panels all have my M-Audio USB audio device assigned. There should be nothing that is "Unknown", yet I can't stop Logic from giving this annoying warning.

    Any hints?
