Universal Serial Bus Controller Registers (Function 2)

This USB host controller interface is fully compatible with

UHCI specification v1.1.

There are two sets of software

accessible registers: PCI configuration registers and USB I/O

registers. The PCI configuration registers are located in the

function 2 PCI configuration space of the VT82C586A. The

USB I/O registers are defined in the UHCI v1.1 specification.
