摘要
通用串行总线(USB)因为其使用方便、传输速度快、支持即插即用等优点,获得了越来越广泛的应用,已经发展成为一种很普遍的计算机与外设的接口。USB驱动程序则是硬件设备连接到计算机系统的软件接口,而windows驱动程序模型(WDM)是windows平台的新一代设备驱动程序模型。文章首先介绍了USB2.0规范,重点提到USB的传输类型和总线结构,然后分析WDM的工作原理和机制,着重介绍基于WDM的USB驱动程序的设计方法,最后给出了PC机对USB设备的应用程序实现。
Universal Serial Bus USB is used widely because of the advantages of convenience higher speed and Plug and Play Function and it has become a popular interface between computer and peripheral device. USB driver is the software interface between them while Windows Driver Model WDM is the latest driver model. First the USB2.0 specification especially focusing on the transfer type and bus protocol is introduced and secondly the theory and mechanism most of USB driver are analyzed and the design method of USB driver is particularly introduced. At last the application between PC and USB device is given.
