最今我接到了开发pc和pocket pc通过usb口通讯的任务。这两个星期我参考了很多方面的资料，特别是AKing大哥写的一些文章。但我始终没有打通这个关口，我贴出我的代码请AKing大哥看看,现在很急，多谢。

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。 , V |, o2 i) a; |

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。 |
