    Don't you have to invert one axis, somehow?

    no, the opitical mouse senses the ball moving and moves the mouse. But the left and right is mixed up. So i use a mouse programs that flips it.

    That's what he meant by asking if you had to invert one axis I'm pretty sure. :D Nice work!

    the first cord senses the buttons and the second cord senses the movement.

    As mice are low-power devices, you can match up the ps/2 and usb wires and solder them together. This would eliminate one cord, and allow for both devices to continue to work.
