As I mentioned before I haven't= done any driver development by now, but maybe it's also a good chance = to get a little bit into that now. Currently the one and only real prob= lem with the driver at this time is that the YUYV and YVYU support seem= s to be broken - it's hard to say because of the heavy over-exposure, b= ut I guess there is something wrong in a conversion or something simple= like that. Fixing only this issue (and maybe the auto-exposure) would = give us everything we need. However, as soon as you have some time to t= ake a look at that feel free to contact me such that we can further tal= k about these things.

Currently I'm a bit absorbed by other higher priority tasks, so I haven= =C3=A2=E2=82=AC=E2=84=A2t been able to update the driver as fast as I w= ould want. We are working towards enhancing the driver so most of the features be = available, but if you have some enhancement suggestion, I'll invite you= to do so. I appreciate your time.
