Universal Serial Bus System Architecture, Second Edition, based on the 2.0 version of the Universal Serial Bus specification, provides in-depth coverage and a detailed discussion of USB. It focuses on the USB protocol, signaling environment, and electrical specifications, along with the hardware/software interaction required to configure and access USB devices. Key topics include: Hot plug support (detection of low-, full-, and high-speed devices) Electrical signaling at the 1.5, 12, and 480Mb/s rates 2.0 hub operation (including split transaction support) 2.0 high-speed protocol (including high-bandwidth and ping transactions) High-speed transceiver test modes Suspend/resume operations Device descriptors Device requests (commands) USB transaction protocols (low-, full-, and high-speed) Bus-powered devices Self-powered devices Error detection and handling Device configuration Device classes This second edition has been updated to reflect the changes in the USB specification from the original 1.0 to the current 2.0. The USB 2.0 specification defines high-speed transactions operating at 480Mb/s that increase throughput by a factor of 40 over the older USB devices. New high-bandwidth, ping, and split transactions have also been added to further increase efficiency of the high-speed protocol. The USB 2.0 specification makes major improvements to USB, while maintaining backward compatibility with 1.0 and 1.1 USB devices. If you design or test hardware or software that involves USB, you wouldn't want to miss the important updates in this book. Universal Serial Bus System Architecture, Second Edition, is an essential, time-saving tool. The accompanying CD-ROM includes an 85-minute USB 2.0 overview video by Don Anderson, featuring an introduction to the basic concepts underlying USB 2.0 bus operation and protocol. Topics covered include terminology, design goals of USB, a review of low- and full-speed operation used by USB 1.0 and 1.1 systems and devices, an introduction to USB 2.0 high-speed transfers, and how USB 2.0 hubs use split transactions to provide backward compatibility to low- and full-speed devices. The PC System Architecture Series is a crisply written and comprehensive set of guides to the most important PC hardware standards. Each title is designed to illustrate the relationship between the software and hardware and explains thoroughly the architecture, features, and operations of systems built using one particular type of chip or hardware specification. 0201309750B04062001
