Issues: 18 - data loss -- one single Receive URB is not nearly enough 19 - nonstandard flow (Option devices) control 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. 29 */ 30 31 #define DRIVER_VERSION "v0.7.2" 32 #define DRIVER_AUTHOR "Matthias Urlichs <smurf@smurf.noris.de>" 33 #define
