由于仅仅通过数据包的截获无法准确判断是硬件问题还是软件问题，针对USB总线设计出信号分析系统可以有效解决此类问题。首先分析了USB通信，描述了USB体系结构、USB物理接口和USB事件；其次对USB总线信号分析系统进行总体设计；最后对系统的软件部分进行了实现，并给出了部分源代码。对于硬件工程人员和软件研发人员都具有一定的积极作用。

Due to the lack of data packet interception to accurately determine the hardware or software problem, for the signal analysis system can effectively solve the problem that the design of USB bus. The first, this paper analyzes the USB communication, describes the system structure of USB, USB physical interface and USB events; secondly, the USB bus signal analysis and the overall design of the system; finally, the software of the system is realized, and gives part of the source code. This paper has certain positive role for the hardware engineers and software R&D personnel.
