Introduction to USB
This chapter presents a quick introduction to USB. The first section in this chapter introduces the basic concepts of the USB specification Revision 2.0. The second section explores the data flow model. The third section gives details about the device operation. Lastly, the fourth section describes USB device logical organization. The full protocol is described extensively in the USB Specification Revision 2.0.
A BRIEF HISTORY OF USB
The Universal Serial Bus (USB) is an industry standard maintained by the USB Implementers Forum (USB-IF) for serial bus communication. The USB specification contains all the information about the protocol such as the electrical signaling, the physical dimension of the connector, the protocol layer, and other important aspects. USB provides several benefits compared to other communication interfaces such as ease of use, low cost, low power consumption and, fast and reliable data transfer.
