你开发的这种软件类似于Palm Desktop Software，负责Pocket与PC之间通讯，我建议你最好先写一个驱动，将USB口虚拟成一个串口，然后直接对串口操作会很方便的。我现在做的程序可能和你相似是一个CDMA模块，通过USB口与PC机连接，然后由驱动程序将它虚拟成一个串口，我的工作就是和这个虚拟的串口通讯。

假如将一个USB设备虚拟成串口的话，那么它的符号名可能是COM3,COM4,或COMn，这根据你当前PC机的配置而定 。它的符号名位于注册表中HKEY_LOCAL_MACHINE\CurrentControlSet中，你可以搜索注册表，另外在2000或以上的操作系统中，你可以到HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SerialComm中看到。

我以前在一张贴子中详细回答了如何利用设备序列号和设备GUID来访问该设备，你可以搜索一下CSDN。你所说的CreateFile不能打通设备，你要查一下，你的符号名是否正确，包括设备序列号和设备GUID是否正确，设备GUID你可以从驱动程序的安装向导文件.inf中找到，设备序列号则需要你到注册表中去找。

不好意思，是因为ActiveSync3.7一直在系统服务程序中运行，占用了驱动程序，所以不能打开设备。我删除了ActiveSync3.7后就可以了。 |
