If the string was instead set to "ep" or "ep-bulk" or something like that, then it would make sense for the auto-configured bulk-out endpoint address to be 2. You should add some printk statements to the ep_matches() routine in epautoconf.c so you can see exactly what it is doing. > however, i only see one SCSI_INQUIRY command being sent out, and it is > not received by the gadget device. There could be other reasons for this, like an incorrect data toggle value. Are you certain the endpoint address is wrong? Can you post the usbmon trace and the output from "lsusb -v" for the gadget?
