| 摘 要： | USB接口以其高传输速率,支持热插拔等特点,在PC机及其外围设备接口中得到了普遍的应用.目前,在便携式设备中USB接口传输也有逐步取代其它接口传输的趋势.而端点在USB开发中的作用又是非常重要的,它是USB主设备与设备间通信流的源点和目的点.不同的端点在信息传输中所起的作用不同,也有着不同的处理过程.本文介绍了端点在不同传输方式下的处理过程及端点在USB开发中的应用,可为开发USB设备及其驱动程序提供一定的参考.

| Abstract: | USB technology has abroad application in PC and its peripheral equipment, because it has a high transmit speed and it supports Hot Swap. Currently, the USB interface transmit also has a trend to replace the other interface transmit in portable system. Endpoints play an important role in developing USB device; it is a source point or a purpose point .of the correspondence stream between Host and Device. Different Endpoints has different action in communication, it also have different processing process. This text discussed the process of different transmit mode and the application of Endpoint in the USB development, it could provide reference for develop USB device and its driver. |
