yeah man, try hooking it up so you can just play with the keyboard. you will want to install a program called "autohotkey", which designates certain keys to emulate mouse movements/clicks.
I have mine set up to do:
F1=FOLD
F2=CALL
F3=BET (minbet)..to bet paticular amount, use keypad, then F3
F4=PUSH
and, the arrow keys select tables (if you quad)
This will walk you through the setup
