The module uses a peripheral USB controller to interface to either a full speed or
high speed USB 2.0 link. The link first tries to communicate to the host system
board at the high speed USB rate (480 Mbps). If not successful, the link reverts to
the full speed USB rate (12 Mbps). This link is used for all communication between
the module and the host system board.
