读写usb 上面的OpenDevice函数就是演示如何根据设备GUID打开一个USB接口的设备，和设备读写通讯的时候就需要了解设备的驱动到底都支持什么方式了。可以使用UsbView工具查看USB设备到底支持几个Endpoint，每个都以什么方式读写。 如果你的设备支持3个EndPoint，0号是控制的，1号是读，2号是写，那你直接读取0号Endpoint，搞不好就会发生重起的问题 -literacy usb above OpenDevice function is to demonstrate how open the equipment GUID a USB interface equipment literacy and communications equipment when there is a need to understand the driving equipment in the end all support the way. UsbView tools can use USB devices in the end View supports several Endpoint. each of the ways to read and write. If your equipment supports three EndPoint, 0, control, on the 1st of reading, writing on the 2nd, you direct read 0, Endpoint, will take place regardless of the starting weight problem
