What is diffrence between machinery mouse and the photoelectricity mouse - Electronic Circuits Projects Diagrams Free

I have made a program with PIC12C508,that connect with the PS/2 mouse,as you see, there are michinery mouse and phtoelectricity mouse. My program sent the mouse tow orders: one is 0XFF to reset the PS/2 mouse, one is 0XF4 to enable the mouse. However, when the PIC12C508 connect with the machinery moues, the program works, but when I connect the photoelectricity mouse,the program can not receive the mouse's data? Can anyone tell me why? what can I do to make my program to work with photoelectricity mouse??

Machinery mouse = ball mouse?
Photoelectricity mouse = optical mouse?

The mice might have slightly different PS/2 protocals as far as start-up goes. Keyboards have the same thing, but I can't say much more since I've never really looked into PS/2 mouse protocals.

Maybe these can help:

My english is poor, it is ball mouse and optical mouse. Thanks to dknguyen. I think the program must have to send several commands to make the optical mouse work and send data to the program, but I do not know which commands.
