异步socket通信C++，对socket基础协议进行封装处理(Asynchronous socket communication C++, on the basis of protocol encapsulation process socket)

用VC++6.0编写的USB通讯测试的程序，可以实现查找PC的USB外设，读取USB外设的设备描述符等功能。对USB通讯初学者有很大的帮助。(Written in VC++6.0 using USB communications test procedure, can be achieved to find PC' s USB peripherals, read the USB peripheral device descriptor functions. USB communication to the very helpful for beginners. )

直接序列扩频通信中采用QPSK调制时，须将产生的串行数据首先串并变换成两路，本程序就是实现这种串并变换！(Direct sequence spread spectrum communications using QPSK modulation, it is necessary to have a string of serial data and converted into the first two, the process is to realize such a string, and transform!)
