Just out of curiosity, what modifications have you made to the driver to get the camera detected ? Having a look at the descriptors, the device shouldn't require an entry in the USB IDs list. > UVC is getting the > formats fine and it creates /dev/video0, but no program I've tried > works.

There is a command line capture program called uvccapture, you could try it. > I'm a c/c++ programmer by profession and I'm happy to put in some effort > to get this working, but I don't really know where to start.

I assume it fails, but you didn't give any error message or failure description. > I've attached the lsusb -v output for reference. The dmesg output is > also attached.

However, the camera supports MJPEG only. It can't stream YUV images.
