Here. I saw something interesting. ALSO, I apparently have something
to fix on the
kernel level.

Notice this line:


 [  3.281559] uaudio0: Logitech (0x46d) product 0807 (0x807), rev
2.00/0.09, addr 1

      [ 10305.047668] uaudio0: Logitech (0x046d) product 0819 (0x0819), rev
        2.00/0.10, addr 2

My line, [  3.281559]. It says "product 0807". We have 2 different cameras?
The last block: (uaudio0): trigger_input failed . What caused this? This is a
GENERIC kernel config. I renamed it and checked it into cvs. I avoid messing
up the original ...
