This book is for developers who design and program devices that use the

Universal Serial Bus (USB) interface. My goal is to introduce you to USB

and to help you get your devices up and communicating as quickly and easily

as possible.

The USB interface is versatile enough for a wide range of peripheral devices.

Standard peripherals that use USB include mice, keyboards, drives, printers,

and audio/video devices. USB is also suitable for data-acquisition units, control

systems, and other devices with specialized functions, including

one-of-a-kind designs.
