You can use MVP 11.0 with Service Pack 1 to disable the USB drive port (USB A format) in the front panel of the printer. This will prevent USB devices from being recognized when plugged in.
NOTE: Disabling the USB drive port will NOT disable the USB connectivity of the printer with computers via the USB port (B format) at the rear of the printer.
The USB drive port can be also enabled/disabled using the front panel interface. For more information, click here.
