* Description of the device:
*
* Interface 0: Contains the IP network interface on the bulk end points.
* The multiplexed serial ports are using the interrupt and
* control endpoints.
* Interrupt contains a bitmap telling which multiplexed
* serialport needs servicing.
*
* Interface 1: Diagnostics port, uses bulk only, do not submit urbs until the
* port is opened, as this have a huge impact on the network port
* throughput.
*
* Interface 2: Standard modem interface - circuit switched interface, should
* not be used.
