Please send me the output of lsusb -v (using usbutils 0.72 or newer) as well.

The driver doesn't process video data at all. The rotation will have to be
done either in userspace (at the application level) or in the camera itself
(it might have a control to rotate the image). The output of lsusb -v might
help me to see if an image rotation control is available.

You're welcome.
