    You’d better try to replace the USB cable and the USB port first to see whether the Driver/computer could find the keyboard.

    You need to confirm whether the computer displays anything at the right corner when you plug off and plug in the keyboard’s USB cable.

    If the computer cannot detect the keyboard at all, you should check the JST connector Pin and the daughter board.

    Since the pins may be bent so you need to bend them back.

    You should bend it as straight as possible, and then push the interface as gently as possible.


    1 Separate the bent pin from the others with a small flat-head screwdriver as below.

    2 Clamp the bent pin to make the pin straight with flat tweezers as below.


    3 You could remove the interface as below to make the installation easier. Push in the JST interface gently. Once you feel any resistance, repeat step1, and 2.

    If the pins are okay, please find another daughterboard as flows in the original box so you could swap the board to have a try.

    Please note you should be very careful to plug in or off the cable of the JST Connector since the connector is fragile and easy to fall off.

    Previous Keys still cannot work after restoring the factory setting and swapping the switches.
    Next My Akko 5075B Plus cannot work after updating the Epomaker 5075B V307 firmware.
