This document defines an industry-standard USB. The specification describes the bus attributes, the

protocol definition, types of transactions, bus management, and the programming interface required to

design and build systems and peripherals that are compliant with this standard.

The goal is to enable such devices from different vendors to interoperate in an open architecture. The

specification is intended as an enhancement to the PC architecture, spanning portable, business desktop, and

home environments. It is intended that the specification allow system OEMs and peripheral developers

adequate room for product versatility and market differentiation without the burden of carrying obsolete

interfaces or losing compatibility.
