(The BisonCam is a different built-in webcam that works.) Someone pointed out that the Logitech may have a microphone built in that makes it come up as uaudio. But even then it doesn't work--comes up as /dev/uaudio0 in the log, but "ls /dev/uaudio0" says it doesn't exist.

Webcam detected as uaudio(4) device
Hi,
I have a USB webcam. No model number on the cam, but looks to be a
Logitech QuickCam Communicate STX.
When I plug it in, I get this:
uaudio0 at uhub1 port 1 configuration 1 interface 1 "Logitech Camera" rev
2.00/1.00 addr 2
uaudio0: audio descriptors make no sense, error=4
ugen0 at uhub1 port 1 configuration 1 "Logitech Camera" rev 2.00/1.00 addr 2
Should it should be connecting to uvideo(4) instead?
