This will be a newbie question, but is it okay to just remove the PS/2 mouse plug (for the pins) like that? And how do you do it, just force it open? Still kinda new to all this.

If you have male/female jumper cables you don't have to cut off the PS/2 plug as I did and use the mouse without any modifications.

This is really cool! Unfortunately like quite a few others, using your code and an MX8733 USB/PS2 chip I noticed my program gets stuck in "while(digitalRead(PS2CLOCK)==HIGH);" inside the PS2Write(0xFF); , when it is called in PS2MouseInit. Any suggestions? The datasheet of this chip says it is both USB and PS2, and is internally switched. Maybe I need to set it somehow to PS2.

The mouse only transmits a change in coordinates and you need to add up those change to get the absolute value of movement. No movement means no change in coordinates, thus the value drops to zero.
