Protocol independent way to reserve and assign preferred port names for session-isolated USB serial/parallel port devices

摘要

Assigning port names based on port name characteristics to multiple universal serial bus (USB) devices where session-level restriction is enabled permits multiple users to connect multiple USB devices to ports using the particular devices preferred port name. Characteristics of a USB device are stored, including a preferred port name. When a user requests connection to a USB device that has been redirected or virtualized, the filter driver at the server attempts to assign the USB device to the preferred port name according to one or more stored characteristics. In this way, multiple users may assign multiple USB devices to the same preferred port name.
