  USB Driver for GSM modems

  This driver exists because the "normal" serial driver doesn't work too well
  with GSM modems. Issues:
  - data loss -- one single Receive URB is not nearly enough
  - nonstandard flow (Option devices) control
  - controlling the baud rate doesn't make sense

  This driver is named "option" because the most common device it's
  used for is a PC-Card (with an internal OHCI-USB interface, behind
  which the GSM interface sits), made by Option Inc.

  Some of the "one port" devices actually exhibit multiple USB instances
  on the USB bus. This is not a bug, these ports are used for different
  device features.
