Abstract
A method and system, used with an extended USB computer system, for locking out USB mass storage devices at the desktop. For lockout activation, a switch at each host computer is set, and causes a host-side lockout process to deliver a downstream lockout signal to the host's associated portal. This signal causes a portal-side lockout process to disallow USB data from a mass storage device from entering the network.
