Not very useful as it doesn't do much more than any other USB hub.

I have a Viewsonic VP950b and it has two USB ports attached to the monitor. There are no instructions in the User's Guide or anywhere else abouy using these USB ports that I can find. If I plug something into one of these ports, nothing happens under Windows Vista or Windows 7. Furthermore under Device Manager I can find nothing listed as to these two USB ports.
Does anyone know what has to be done to get these ports to be operable ?
