using 2 keyboards

I'd like to play the game with my friend at the same PC.
Both my friend and me already got used to play with keyboard and found that joypad is not very convenient. So I tried to use a PS/2 keyboard with a USB keyboard. But at the controller selection screen, only one keyboard shows up.
Does anyone know how to play with 2 keyboards?

same problem with me........but i have played with a friend of mine last january using one keyboard like we always did since the early live series....he set the configs up.......but now he's abroad and i have no way in contacting him.......just be patient i know some guy will pop up and help us out

i dont believe its possible to play with 2 keyboards.
