This USB module is designed to serve as a compound device. An
embedded full-speed device function is combined with a hub in a single
USB module.
For the hub sub-module, five basic properties can be supported by the
hardware or the software: connectivity behavior, power management,
device connect/disconnect detection, bus fault detection and recovery,
and full/low-speed device traffic control. Endpoint 0 of the hub sub-
module functions as a receive/transmit control endpoint. Endpoint 1 of
the hub sub-module functions as interrupt transfer to report the device
change state.
