Document Overview:


This document serves as a complete walkthrough for installing a dedicated USB host controller card into a system running Windows XP Professional.

The card being installed is a four port (three external and one internal) USB Interface card. The manufacturer of this card, Mercury employs a via chipset to control system functions of the card. Using this card, one can expand the existing USB capabilities of a system by adding four additional USB devices through a single interface.

This card also eliminates the need for a seperate power supply normally required by external based USB hubs. The card's power source comes from the system's motherboard. More specifically, a PCI slot meeting the 2.2 revision is required for a successful installation.

The Mecury PC based KOB USB2V employs a VIA chipset and adds three external USB slots and one internal USB slot.
