Now in its third edition, this developer's guide to the Universal Serial Bus (USB) interface covers all aspects of project development, including device programming and host application software. This book shows how to transform the information in the USB 3.0 specifications into functioning devices and application software that communicates with the devices. To help build a foundation for design decisions, developers are guided in selecting device-controller hardware. Developers will also learn the benefits of the USB interface, its limitations, and how certain design choices made at the beginning of the project can reduce development time. Recent developments in host and device hardware, more detail on the standard USB classes, application examples using Microsoft's .NET Framework, and information on developing dual-role devices using USB On-The-Go is provided in detail.
