I have tried to do this using Rapid Install from Symantec and I still have the problem of needing admin rights to install this driver and on each usb port.
From all the stuff I have found on the web, it is because of the unsigned drivers.
So no joy, two devices (an Avervision document camera and a Boreal microcsope) times 60 laptops, time 4 USB ports equals 2 unhappy techs!
