Motorola Phone (V3), rev 1.10/0.01, addr 2 Interesting - the port is disabled and then you get the ugen message. Are you shure that these messages belong together? If the device really refuses set_config it is a very fundamental USB violation. I would like to know if the device is still processing requests. What does usbdevs -v say? usbdevs -v asks the device to descriptor string, so we will know if is is running. A hang device would hang output of usbdevs at a given for a few seconds until timeout. -- B.Walter BWCT http://www.bwct.de bernd@bwct.de info@bwct.de
