This book guides developers in designing and programming small, embedded systems that access USB devices. Topics include how embedded USB hosts differ from USB hosts in PCs, how to choose a hardware and programming platform for a project, understanding USB host programming in Linux embedded systems, how host applications can access USB devices of all types, and how to design a system that can communicate with both USB hosts and USB devices. Example code shows how to read and write to files on drives, get user input from keyboards, communicate over virtual serial ports and Ethernet bridges, record and play audio and video, print documents, use a USB display monitor, and access vendor-defined devices of any type. The example code runs on embeddede Linux systems including the popular BeagleBoard-xM open development board. This book is a companion to the author's best-selling USB Complete, now in its Fourth Edition. The author¿s website has program code, articles, and other information of interest to USB developers.
