3H Dual Arcade Controller

[GeraldVegas]

I am currently in the process of converting a PandoraBox cabinet into a Mame machine and so purchased a Jamma  -> USB card.  The card is seen in windows (10 64 bit) as two 3H Dual Arcade controllers but when I go to check the joysticks or buttons the PC is not receiving any of the inputs.

I could have a broken card or the wiring in this cabinet is not standard Jamma.  Can anyone tell me if the wiring for PandoraBox is standard? (When I connect everything back up it all works with the PandoraBox cartridge).  I have uploaded a pic of the card incase anyone recognises it.  (All I did was remove the Pandorabox cartridge and connect this card in its place.)

Appreciate any help / support!
