Not all PS/2 mouse can be changed to a USB mouse, you can change the characteristics of the PS/2 mouse:
A. early PS/2 Mouse board generally with two integrated circuits, (a photoelectric sensor, a key or USB protocol conversion, and a 24M crystal oscillator (hereinafter referred to as: Crystal oscillator)
B. later PS/2 Mouse only a piece of photoelectric sensor chip, but also has a 24M crystal oscillator (abbreviation: Crystal oscillator).
C. Non-professionals should not try. Damage to the mouse is not responsible for OH.
Can change the PS/2 mouse generally with a crystal oscillator (abbreviation: Crystal oscillator), if the picture is changed, but the computer detected as an unknown USB device, and not a mouse device, that the PS/2 mouse can not be changed to a USB mouse.
Transform the PS/2 interface mouse into a USB interface mouse
