Disabling user USB access
In some situations, you might want to disable the ECP’s front USB receptacle. Disabling the USB
receptacle prevents users from using or saving documents to USB drives using the ECP’s front USB
receptacle. The other USB receptacles won’t be deactivated since they’re required for your
interactive whiteboard and computer connections to function.
Follow these instructions to remove and cut the case on the ECP, and then remove the USB jumper
switch to disable the ECP’s USB receptacle.
