Thanks a lot for the patch. Before I test it, could you please send me the complete USB descriptors of your camera ? You can get them with lsusb -v (make sure you use usbutils 0.72 or newer - 0.73+ is preferred). > PS.

The 5.2M resolution is probably the result of software interpolation. Marketing BS, as usual.
