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 | |
7c1c2f73 | 19 | - nonstandard flow (Option devices) control |
14f76cc7 MU |
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. | |
