4.0 Functional Description
4.1
Universal Serial Bus (USB)
The 82C862 controller supports a PCI-based implementation of Universal Serial Bus utilizing the OpenHCI core developed by
Compaq. The logic core consists of two USB host controller modules (making the 82C862 part a multi-function PCI device),
and a PCI interface controller.
Each USB host controller module contains an integrated root hub that supports two downstream USB hubs or devices.
Keyboard and mouse legacy support are also included for DOS compatibility with USB devices. This legacy support operates
in conjunction with the primary host controller module as described later in this document.
This document must be used along with the following public domain reference documents to get the complete functional
description of the USB core implementation.
USB Specification, Revision 1.1
OpenHCI Specification, Revision 1.0a
PCI Specification, Version 2.1
A functional block diagram of one of the two USB controller modules is given in Figure 4-1. The other is identical.
