Laptops :: AccuPoint pointing device detection?

i've managed to get DSL loading fine on my toshiba sat 2590CDT with both a ps2 and usb mouse, now i'd like to figure out how i can get it to recognize the accupoint pointing device...? (it's that little red or green "joystick" sitting uncomfortably in the middle of the keyboard)

not terribly important but i'll be a very happy person if i can use accupoint and my external mouse simultaneously like i can in win98.
