generic hid control,find your HID device and your can read and write command to test.

本源程序介绍如何应用VB.net读写USB接口，能够做到自动检测USB在线与否，之后就可像读自己硬盘一样去读写数据，实用方便

利用USB接口进行通信的数据源码MemberIndex = 0 Do 'The cbSize element of the MyDeviceInterfaceData structure must be set to 'the structure's size in bytes. The size is 28 bytes.
