I am experiencing the same problem after upgrading to 11.10. I have a logitech webcam :
Bus 002 Device 006: ID 046d:08c3 Logitech, Inc. Camera (Notebooks Pro)
Sound is muted, no sound device is reported in the sound menu, banshee crashes Firefox is much slower (video with sound playing in youtube)
I get two messages in kern.log :
3:3:3: cannot set freq 16000 to ep 0x86 3:3:3: usb_set_interface failed
The problem is appears randomly but quite often.
