Comment 30 for bug 459445

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.
