I was not referring to positive knowledge about the devices you are testing with. I was having dark thoughts about the other devices they are sharing an ID with. But Bjorn's testing has resolved that. In that case we can indeed not penalize the compliant devices for the broken ones. One question, though. Your approach of simply doing nothing if config 0 is to be selected again is a bit brutal. Have you considered resetting the device and stopping the reenumeration right as a config is supposed to be chosen? Regards Oliver
