Hi Hans,

BTW, I don't think the exposure and gain controls use the right registers as they are coded in the actual gspca pac7302 subdriver. The ms-windows driver uses the registers (3-80 / 3-03), (3-05 / 3-04),
3-03, 3-04 and 3-05 are already known and they all influence framerate / exposure in some way. I've also ran some tests with 3-80, again it influences framerate in some way (*). We already have a well tested and working, fine-grained way to control exposure so I think it is best to leave things as is exposure wise.
(3-12)
3-12 is interesting, it is a new gain control. The pull request I've just send (with you in the CC) contains a patch to improve gain control using both 3-10 and 3-12 together.
and (1-80)
1-80 is compression balance, since our decompression code for higher compression settings (markers > 68) still is not perfect this is best left untouched. *) Note I've documented all registers I've ran tests with as part of the patchset for which I've just send a pull request.
