=46OA, there is no need to send the request twice and there is also no need to send it to sane-standard! Regarding your problem, it seems, that the underlying USB subsystem makes some troubles - could you check the system log? What version of libusb are you using? When using 0.1.10, try downgrading to 0.1.8. Ciao, Gerhard
