Every Windows 98 and Windows 2000 computer contains Universal Serial Bus ports for connecting to a variety of peripherals. This guide takes the pain out of designing for this popular interface with specific, detailed examples that show how to develop USB devices and the applications that communicate with them. How the USB communicates with the PC, deciding if a project should use a USB interface, choosing a USB controller chip for peripheral design, and determining code which USB peripherals need to communicate with Windows applications are covered in detail. Reflecting the changes in the newly released USB 2.0 standard, this book also includes a complete project that shows how to develop a custom USB peripheral from start to finish.
