USB interface
The USB interface is the only path for communication between the host and
module.
The interface complies with the Universal Serial Bus Specification, Rev 2.0.
Features of the USB interface include:
• Support for full-speed (12 Mbps) data rate
• (MC8201/MC8700/MC8790/MC8790V/MC8791V/MC8792V/MC8795V)
Support for high-speed (480 Mbps) data rate
• Transfer of general, phone diagnostic, and over-the-air data between the
module and the host
• Enumeration of the module as a set of Modem (MC57xx) or COM (MC57xx
and MC8xxx) ports, using host Windows drivers
