This USB module is designed to serve as a low-speed (LS) USB device
per the Universal Serial Bus Specification Rev 1.0.
Three types of USB data transfers are supported: control, interrupt, and
bulk (transmit only). Endpoint 0 functions as a receive/transmit control
endpoint. Endpoints 1 and 2 can function as interrupt or bulk, but only in
transmit direction.
