hi fdrph,
with windows-enabler you must be able to change the
gain control slider.Did you try windows-enabler??
Soooo all one would have to do is create a progam that sends these requests to the camera right? then why havent people done this before?
Maybe the majority of people don't use uvc because they buy a webcam with software.
I don't have any experiance with uvc, but like I wrote before, if something is grey-out you should be able to change it with windows-enabler.
This is all I can do for you for now, maybe someone else knows more about it and has some sollutions for you.Or has the knowledge to make a program to enable/disablel auto exposure in uvc.I don't have the knowledge.
If you find a solution yourself it would be nice if you share it with us.
