General Description
These devices are Plug and Play Windows 2000 and
5-button 3D USB+PS/2 Mouse controllers. Fully sup-
porting the USB standard request as well as HID Class
Request version 1.1, they are compatible with Microsoft
Intelli 3D or Windows 2000 5 key PS/2 mouse. The
Z-axis can support two kinds of scroller input, both
optomechanical and mechanical. The devices require a
minimum of external components to implement a 3D or
Windows 2000 5 key USB plus PS/2 mouse. All of the
device features in combination provide a versatile
Holtek MCU with fully integrated USB interface logic.
The USB is specified by the Universal Serial Bus Speci-
fication V2.0.
The USB vendor ID for the devices is defined as
