This has been driving me crazy.
All the lab machines at my site run as a restricted domain user. Some USB drives will work just fine. Mount, assign drive letter, and auto play.
The problem I'm having is that a few thumb drives have recently started giving the message. "Unable to install new hardware. Contact your Administrator."
At first I thought it was the Autorun kicking up something like the Lexar encryption software. But no, it was the plug & pray framework crapping out as a restricted user.
If I install the drive as admin, then it will work fine. But as restricted, it will not.
I've done regmon + filemon to find what areas I need to relax permissions on to no avail.
The event log doesn't list any possible cause. The only thing that does is the %systemroot%\setupapi.log
After exhaustive searching of the errors found therein, I have thrown up my hands.
Has anyone else ran into this problem and found a solution?
