+  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) and multiplex (Sierra) 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.
