请教：如何解决“没有替设备实例指定一个功能驱动程序的错误”

我用的是DriverWorks做的USB设备驱动程序，硬件那边不是我做的，要实现中断写和批量读的功能。我参照driverworks里的实例和武安河那本新书的例子对生成的驱动程序修改后，已经编译生成了sys文件。而且参照了不少的inf文件修改了生成的inf文件，但是现在安装时出现了：
安装设备时，出现了一个错误
安装失败，因为没有替设备实例指定一个功能驱动程序的错误
我已经在论坛上搜索了有关这方面的帖子，但是也没有具体的解决方法。
我不知道该如何解决。
我是个新手，对开发工具也不熟悉，恳请各位帮帮我，多谢了！
以下是我的inf文件的内容。

请各位高手指导。

看DDK sample,然后自己加上去呀 !!
