1.1 USB Overview
USB is an open industry standard, providing a simple and inexpensive way to connect up to 127
devices to a single computer port. Keyboards, mice, tablets, digitizers, scanners, bar-code
readers, modems, printers, and more can all run at the same time. USB devices plug into any
platform that supports the standard, from notebooks to desktop PCs to workstations.
USB is a dynamically reconfigurable serial bus with an elementary data rate of 12,000,000
bits/sec, based on off the shelf, low cost micro-controller technology. Its modular layered
software protocol supports sophisticated device drivers and application programs.
Please refer to the USB Specifications for details on the USB protocol. The USB specifications
are available from the USB Implementers Forum at:
