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?
Some info on my end:

...that "device v0461 p0815 is not supported" is not very
promising... I wonder if that is the spca561 driver saying
that...
Thanks,
Braden
