VSO device (Variable Speed Overdrive)is the burn engine used by certain software from VSO. Have you installed Blindwrite Suite? This provides a VSO Devices entry in Device Manager and installs a Patin Couffin driver as well.

Have you installed the VSO Inspector ? If you don't need it, remove it. Click Start -> Programs -> VSO -> Drivers and click on Remove, then reboot your computer.
