【摘要】 采用PDIUSBD12芯片的基于USB接口设备驱动程序,模型最上层的函数驱动程序,管理应用程序与较低级总线驱动程序间的通信。底层的总线驱动程序,管理函数驱动程序与设备硬件间通信。中间的过滤器驱动程序,辅助函数驱动程序与总线驱动程序。USB设备函数驱动程序与总线驱动程序,使用I/O信息包处理USB的通信。同时,根据USB通信协议,使用DriverWorks的工具模块进行WDM设备驱动程序的开发。更多还原

【Abstract】 The driver of the device based on USB interface which applied PDIUSBD12 chip,whose function driver at the top of the model,manage the communication between application program and the bus-class driver of the lower layer.The bus-class driver of the bottom manages communication between management function driver and the device hardware.The middle driver of the filter assists function driver and bus-class driver to operate.The USB device function driver and bus-class driver use I/O request packet to deal with the USB device communication.According to the USB communication pact,using DriverWorks tools module to develop the driver of the WDM device.更多还原
