Abstract: This paper presents the design and implementation of a distributed USB monitoring system. Aiming at the complexity and low commonality about development of USB driver, the system implements a scalable USB HID(Human Interface Device) data access interface by using the method of IRP interception. It achieves a technique to sniff the data of hardware under the premise of non-impact on effective of I/O transmission, and takes a simulation experiment as an example to test this method. Experimental result shows that this method simplifies the development of the drive, and supplies the encapsulation of data and a scalable interface.

摘要： 描述分布式USB监控系统的设计与实现。针对USB驱动开发复杂和通用性较差的问题，提出利用IRP拦截的方法实现一个扩展的USB HID(人工接口设备)数据访问接口，在不影响接口I/O效率的前提下实现对硬件数据的侦听，并以仿真实验进行验证。实验结果表明，该方法能简化驱动开发流程，提供数据的封装和扩展接口。
