By I remmember from USB Spec, endpoint 0x81 should be IN (MSB 1) and endpoint 0x2 should be OUT (MSB 0). I don't what are exactly the side effects of inverting them... Did you write the device firmware also? If not, probably you should swap the values of PLUG_BULK_IN_EP and PLUG_BULK_OUT_EP. If so, revise your fw source code to follow the correct USB Spec. After that, report the result to the list.
