Currently either of them ie. f_acm (as part of composite driver along with ums) or gadgetfs (as independent module) can be loaded, which allows only one active USB function at a time. If gadgetfs can be made as a composite function then I can have both functionality at same time. The use case for this scenario :- user can listen to media (from device) as well browse internet (via device modem) on PC while device is connected to PC over USB. -- Regards, Rupesh Gujare -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
