just the player 2 number 5 button lights up nothing else, but when I do the keyboard test or notepad nothing happens anyway and I started my ground on the player 1 controls and daisy chained 2 player 2's last button which is 6, so that being your theory would'nt all the other buttons but player 2 5 and 6 work. its as if windows is not picking up the minipac, you know when you plug a pnp device in it makes that "da dum" noise, well it does it for the seperate led board but not my mini-pac board.
