Yeah,
Atleast I can control the focus with the ioctls. Dont know the units though. Something in the range of 550 seams to be focusing very close, whereas something like 150 means infinite.

But when I try to set V4L2_CID_EXPOSURE nothing happens. I tried fiddling with the V4L2_CID_EXPOSURE_AUTO control as you suggested but the driver doesnt seem to support this.

EDIT: Wait, now it works. Strange
