Andrew Hi,
Could you try luvcview or guvcview instead, xawtv doesn't work for me either.
I think it may have something to do with libv4l2, or then just some
configuration problem.
Best regards,
Paulo

I recently purchased a Creative Webcam Live! Cam Notebook Ultra. It has a
different product id than some of the ones i've read about. I think it might
be a UVC webcam because the uvcvideo driver loads but i cant get an image
out of it.
