OK, I'm stumped for the webcam I've got.

After sorting out the shenanigans between what is V4L and V4L2, it works
fine but only advertises up to a resolution of 640x480 (VGA). And it is
very definitely using USB2.

It doesn't appear when xsane scans for devices.

So, how do you get to see more than just 300k pixels of the supposed 4M
pixels?!

It uses the gspca_sn9c20x module driver.


Anyone else other than Jim had any success?

Cheers,
Martin
