This problem may be related to v4l2 ctl exposure-auto-setting fails which has not been answered and has remained opened since November.
I am using the c525 with OpenCV, and for my application to work properly, I need to disable auto exposure, the exposure automatic priority, and the auto focus.
Default settings from Video4Linux Control Panel: 
When I try and change exposure auto priority: 
I am running my application in a VMWare Player instance, running Ubuntu 12.04 x86_64, with a Windows 7 64 bit host.
I currently don't have the option of doing a full install of Ubuntu, but I don't see why this would be an issue with running inside a virtual machine.
Update:
I fiddled with the settings, and was able to change auto exposure priority, but then inside OpenCV, I get a lot of device timeouts.
