摘要
USB即通用串行总线,是一种支持在USB主机和USB设备之间进行串行数据传输的通信协议。通过USB设备接入检测、总线枚举步骤、设备类配置、描述符介绍、描述符程序实现等方面,介绍和分析USB总线的初始化过程。
USB stands for universal serial bus. It is a communication protocol which support the serial data transmission between PC and USB devices . This paper discusses the initialization of USB as follows the access testing of USB devices,steps of bus enumeration,configuration of USB devices,introduction of descriptors and realization of descriptors by program.
