The controller is based on a Corigine USB 3.1 IP core that is dual-role capable (device and host), used here in device role. It provides SuperSpeed (5 Gb/s) or High-Speed (480 Mb/s) operation, and supports control, bulk, interrupt, and isochronous transfer types across multiple configurable endpoints.
