This is probably ConsoleKit/PolicyKit in action. When you log in sat
at the machine, you're a console user with physical access to the
machine, and so you get permissions to access the hardware. When
logging in remotely the permissions don't get set to allow you to
access connected hardware. I suggest having a read about
ConsoleKit/PolicyKit and working out what policy you need to change to
get the permissions you want when logging in via VNC.
