摘　　要：针对USB通信易受外界干扰而出现异常的问题,论述了强电干扰对USB通信的影响,并提出了一种基于API的自动恢复USB通信的方法。该方法能在USB受到强电干扰,出现通信异常后自动恢复USB的通信,并能使开发人员无须关注USB的底层驱动和协议,从而高效快捷地开发USB设备。Aiming at the problem of anomaly of USB communication incurred from outside interference, this paper describes the impact on USB communication from strong electricity interference. A method of self-recovering USB communication based on API is also introduced here. The method can recover USB communication from abnormal status due to strong electricity interference automatically and makes engineer develop USB device swiftly and efficiently without knowing about the details of the USB low-level driver and protocol.

关 键 词：USB 自动恢复 API 强电干扰
