Yes this version includes the fix. Is it possible for you to take a wireshark capture on the usb bus when the probing of the device is made by the kvaser_usb driver? Can you also check if the device is correclty probed by the Kvaser leaf driver, i.e. the one you can find on the kvaser website? Thanks, -- Olivier
