Some devices will only work if clear stall is issued as a part of a reset sequence. This has been discussed before on this list. In the file "/sys/dev/usb/usb_subr.c" in the function "usbd_setup_pipe" could you change: err = usbd_clear_endpoint_stall(p); into err = 0; /* usbd_clear_endpoint_stall(p); */ Then recompile the USB module: "make -C/sys/modules/usb depend all install clean" Reboot and see if there is any change.
