| |
| 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. |
