I have not tried using both ports simultaneously. If your approach did not function, could you try coping to the memory as a seperate operation, then downloading (reading data from the memory device from it's other port) into your target device? If this works, there may be an inherent restriction regarding being able to handle input and output at the same time. BTW, good question! Best wiches.
