Hi Braden, James --

I tried that webcam with Ubuntu 12.10 last week, with no luck;
neither cheese nor the guvc camera controller could see it.

 Hmmm... I tried motion and fswebcam, and they cannot seem to
 communicate with it.  Motion complains about an
 unsupported pallette (GBRG), and fswebcam says it times out
 waiting for frames.  The same thing happens if I try
 this LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so trick I have
 seen online.
 I wasn't able to talk to it on my laptop either.
 Both are Arch linux though, i.e. similar kernels and drivers
 installed I suppose, so perhaps I should see what happens on
 another machine, e.g. Gutenberg.
 Do you happen to know what driver you were using?
