Driver for Goldtouch 10-Key Numeric Keypad

Question

Anyone know of a driver for this keypad? I didn't need one when I first plugged it in. It worked for a while, but not it does not. There's no way for me to see if my intel Mac (OXS 10.4.10) even recognizes it. I tried plugging it into another Mac (PowerPC) in our office and works there. Any ideas?ThanksJeanette
