在哪里配置代码中的端点？

嗨，伙计们。我刚开始用FX2项目。我有一些关于端点配置的困惑。我的困惑如下：对于FX2的高速模式，默认描述符提供4种不同的接口配置，并且在每个配置下，端点的特征是不同的。因此，在这种情况下，我把端点配置的代码放在哪里以支持多个接口？提前感谢。最好的问候，埃里克

          hi, guys and gals.   
I have just started projects with FX2. I have some puzzles about the endpoints configurations. My puzzle follows below:   
For the high speed mode of FX2, the default descriptors provide 4 different interface configurations, and under each of the configurations, the features of the endpoints are different. So under such cases, where do i put the codes for the endpoints configuration in order to support multiple interfaces?   
   
thanks in advance.   
   
best regards,
