Absolutely correct!

Without pointing fingers, let's just say, Microsoft LifeCams will ONLY accept certain values, everything else will end up with over exposure.

As an example, I used V4L2 commands to set exposure. Only the following work:
5, 9, 10, 19, 20, 39, 78, 156, 312, 625, 1250, 2500, 5000 and 10000. Nothing beyond 156 works for 30FPS.

The saddest part of this is that if you query the camera for values it will accept, it reply's with "5-20,000".
