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。

Pocket与PC连接肯定有驱动的，如果驱动程序没有将Pocket虚拟成一个串口，你也可以直接通过设备GUID和设备序列号进行访问，详情你参见我专栏上的一篇文章。当然了，通过虚拟串口来访问设备肯定要方便，简单些。 % F6 i5 X- C/ a. L& f

我得这款pocketpc默认只支持使用usb与pc相连的，而且activesync3.7就是使用usb传输数据的。如果我自己写驱动的话，不仅不熟悉而且很可能activesync3.7这个软件就使用不了。我只需要利用它的驱动。你的专栏上的那篇文章我也看了，我就是模仿你的写的代码，但就是到createfile这步就不行了，我的同事是用palm开发类似的程序，也是到这步就行不通了，是不是有其他的原因?; \6 E% e5 x K8 U
我还想问问如果驱动程序将pocket虚拟成串口，如何查看它的符号名呢？ 7 G6 b U- Z6 |0 u! s7 ~

, H3 i7 W: z2 L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。 & s- U$ g; t! l$ W5 b! z# u/ z3 F3 _

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。 M. g+ D+ p" L& p0 r. w
