2 USB Driver for GSM modems

15
16 This driver exists because the "normal" serial driver doesn't work too well
17 with GSM modems. Issues:
18 - data loss -- one single Receive URB is not nearly enough
19 - nonstandard flow (Option devices) control
20 - controlling the baud rate doesn't make sense
21
22 This driver is named "option" because the most common device it's
23 used for is a PC-Card (with an internal OHCI-USB interface, behind
24 which the GSM interface sits), made by Option Inc.
25
26 Some of the "one port" devices actually exhibit multiple USB instances
27 on the USB bus. This is not a bug, these ports are used for different
28 device features.
