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.
