目前，PC/104 与PC 机之间的通讯一般是以串行通讯或者并行通讯两种方式来实现的，
然而USB 通讯正以其高速性和连接灵活性等优点而被广泛关注。为实现PC/104 与PC 机之
间的USB 通讯，本文基于USB 总线接口芯片CH375 设计了PC104-USB 转接板，详细描述
了通讯中涉及的以伪中断方式发起上传数据流，以下传API 发起下传数据流的通讯方式，并给出了相关程序代码。

Abstract: At present, communication between PC104 and PC is commonly realized by way of
serial communication or parallel communication, however USB communication enjoy great
popularization with many advantages such as high speed, joint flexibility and etc . In order to
realize the USB communication between PC104 and PC, PC104 transfer card is designed based on CH375 chip, then the way of that launching uploading data stream with pseudo interrupt mode and launching downloading data flow using API is mainly described. Finally the relative procedure code in the method is provided in the article.
