I forgot to mention that I have attempted to connect the touchpad to my pc's ps2, and I have used the following schematic for the ps2 port connections : PS2 keyboard and mouse mini-DIN-6 connector pinouts
And the touchpad didn't work there either.
Also my ps2 cable's colors seem a bit strange (at least strange to me).
Orange = +5v
Red = Ground
Yellow = Clock
Black = Data
Maybe that is insignificant and the colors are random...
