This is not a serial protocol, but an improperly labelled CDC Data protocol. It should be left unhandled until we are able to figure out how to use it properly. That is doable. It is very close to standard CDC ECM (together with the matching control interface labelled 0xff, 0x01, 0x09), and can be handled by either a slighly modified cdc_ether or a derived driver. (for the record: The other two additions are OK) Bjørn -- 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
