Not seeing all the debug messages. Did you set `uaudiodebug' to > 0?

`drvctl -d uaudio0' will detach uaudio0 & its children audio1, spkr2.
A second `drvctl -d uaudio0' will then produce that `DRVDETACHDEV: Device
not configured' error.

But, neither should cause video0 to detach. You didn't unplug the webcam,
did you? Or, is that USB port wonky? Webcam cable/connector OK?
