I have the same camera, however as I've researched, we're in the unfortunate boat of some work, and some do not. I notice however that you are not using the gspca module?
I first tried it with the logitech quickcam driver without luck. I suggest downloading the gspca driver from
http://mxhaard.free.fr/ . Install as it has noted and modprobe gspca (perhaps modprobe spca, check the readme). That site also has a couple of applications for testing the camera out such as spcaview. I suggest downloading one to give your camera a quick test. Make sure you're part of the video group, or you may have permission problems with v4l.
This worked perfectly for me when using the gspca driver.
Good luck,
Coto
