evc连接sp的问题

买了个dopod 565,用ActiveSync同步没问题,但是用evc4就是连接不上,报"Unable to load
device side components.",但是连接模拟器是可以的。跑到news group里查,建议的方法五花八门,重装这个那个的

最后耐心的一个个看下去,总算找到正解。原来是要为设备文件创建一个签名证书,使用Windows CE Tools\wce420\SMARTPHONE 2003\Tools\spdps.exe。
SDK中原文:
The security features of Smartphone devices make it necessary to sign certain files that are used to support the development and debugging process. During the installation of the Smartphone SDK, this process is performed automatically for the files that the device emulator uses. However, when you want to enable a real Smartphone device for testing and debugging, you will need to complete this file-signing process manually.
