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.
