Linux Device Drivers: USB Drivers

Overview

The Universal Serial Bus (USB) is a connection between a host computer and a number of peripheral devices. It was originally created to replace a wide range of slow and different buses - the parallel, serial, and keyboard connections - with a single bus type that all devices could connect to. USB has grown beyond these slow connections and now supports almost every type of device that can be connected to a PC. The latest revision of the USB specification added high-speed connections with a theoretical speed limit of 480 MBps.
