Is exposure_absolute supposed to be in microseconds...?

Yes.

According to the docs V4L2_CID_EXPOSURE_ABSOLUTE is in 100 usec units.

 OTOH V4L2_CID_EXPOSURE has no defined unit, so it's a better fit IMO.

Way more drivers appear to be using EXPOSURE than EXPOSURE_ABSOLUTE, too.

Done, switched to V4L2_CID_EXPOSURE. It's true, this control is not
taking 100 usec units, so unit-less is better.

Thanks. If you know the units, it would be of course better to use
right units...
