1-12 Chapter 1: General Overview
Glide Pad
The PS/2 keyboard has no Mouse, Trackball, or Glide Pad capability.
The USB keyboard supports an optional Glide Pad. The Glide Pad is a
standard USB HID mouse-type device, seen within the host computer
software as separate from each of the other independent USB devices.
As with the other USB PnP components of the USB keyboard, the
presence or absence of the Glide Pad is easily detected in the host
computer.
Fingerprint sensor
The USB keyboard has been designed to accommodate a Fingerprint
Sensor Module. This module replaces the Keylock module, and
operates as another independent USB device through the internal hub.
