Is it possible to add a quirk with usbconfig after the device is already detected? devd won't work since it won't say anything as config 0 won't attach to any driver and ugen isn't listed there. Also the devd data would be missing the bus number. -- B.Walter <bernd@bwct.de> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
