It will not work if you use stock firmware; instead, you must flash it with modded or custom firmware, such as Braiins OS, if you want the hashboard to detect, as each hashboard has a unique serial number. The hashboard will not recognize the serial if it is not registered on the control board.

To bypass that issue, you need to boot it or flash the control board with Braiins OS to make them work.
