Matthias Urlichs | 14f76cc | 2006-06-02 11:48:56 +0200 | [diff] [blame] | 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 |
Matthias Urlichs | 7c1c2f7 | 2006-07-20 04:56:00 +0200 | [diff] [blame] | 19 | - nonstandard flow (Option devices) control |
Matthias Urlichs | 14f76cc | 2006-06-02 11:48:56 +0200 | [diff] [blame] | 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. |
