使用的芯片是pl2303,wince500下厂商提供驱动，但wince600没有，因为不了解USB，整个过程困难重重，参考大量帖子，有用的很少。
usb 转为 com6
首先要移植public下usbser的代码，生成USBSer.dll,这个太重要了
1、复制Public下的USBSER整个文件夹到C:/WINCE600/PLATFORM/SMDK6410/Src/Drivers/Usb；
2、在PB下打开命令行工具，并切换路径到当前USBSER文件夹所在的路径，使用命令 sysgen_capture -p common usbser 转换完成后，将在当前目录下会生成sources.xxx的文件，由于我们只需要生成usbser的目标文件，因此可以将其他sources.xxx文件删除。
3、下面的工作就是如何生成dll文件：
实现方式一：（使用LIB生成DLL）
（1）在当前目录下新建一个文件夹XXX（USBSERDLL），把sourcess.usbser拷贝到该新建文件夹并重命名为sources；
（2）打开该sources，将DEFFILE宏修改为DEFFILE=$(TARGETNAME).def；
（3）从USBSER文件夹将usbser.def文件和makefile文件复制一份到USBSERDLL，即USBSERDLL文件夹中现在只有Makefile、sources和.def文件；
（4）在USB文件夹下的dir文件中，加入USBSERDLL、USBSER的编译选项信息；
（5）在USBSER的sources文件中删除WINCETARGETFILE0=$(_COMMONOAKROOT)/lib/$(_CPUINDPATH)/$(TARGETDEFNAME).def；
（6）build Usb文件夹，把编译报错的头文件（主要是在pubic下未包含的文件，该例子主要是缺少usbserv.h、usbinstl.h和usbclientfunc.h）复制到USBSER文件夹下，rebuild Usb，OK！

原来一直以为只要生成了USBSer.dll 就万事大吉了，其实我错了，这只是第一步而已。
