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.
