Is there anyway to change it so its not self powered? It is what the device tells, maybe config 1 is just the configuration for running on own power. A device may have several configs with different power/feature sets. A freshly contected device is considered unconfigured. You can use /dev/ugen to set a different one - well if your device really has different ones. Just open(2) the device and use UR_SET_CONFIG ioctl. The disabling mesage is still very strange, as the device is not disabled. Unless you need it for something else you might as well try a kernel without ugen support. -- B.Walter BWCT http://www.bwct.de bernd@bwct.de info@bwct.de
