[pwc] Logitech QuickCam Pro (Black Ring)

["John Stoffel" <>]

I've got an old Logitech QuickCam that I'm trying to make work.  I'm
running Debian with a 2.6.15-rc7 kernel.  Haven't upped to 2.6.15
quite yet, though it's ready to roll.  

The camera has a USB id of:

        Bus 004 Device 005: ID 046d:d001 Logitech, Inc. QuickCam Pro

so I hacked the pwc-10.0.10 code to recognize it, as the patch below
shows.  The one issue I have with the code is the random mixing of
case in the various vendor_id sections.  I think they should all be
made ocnsistent in the code one way or another.  Any problems
submitting a patch to do so?

So while it recognizes it now when I plug in the camera, I can't use
xawtv or gqcam to grab video.  Here's my output from dmesg plugging it
in, and trying to use gqcam -v /dev/video0 and xawtv -v /dev/video0 as
well.  Any hints?
