STM32 USB 在win7下安装不了 winUSB的驱动

我用的芯片是STM32的USB，上位机用的驱动为winUSB的驱动，自定义了一个应用，在win xp下能够正常安装驱动使用，但在win7下就出现了提示错误：设备无法启动（代码10）。详细的BUS Hound的捕获的枚举如下：

最后一步总是出现 bad parameter的问题，但放在win xp下，set config之后就能正常运行了。
后来还用了winUSBtrace去看log，错误如下：
[1]0004.0030::03/16/2011-14:30:39.740 - DriverObject 0x878DC638

看情况像是win7的下的USB协议要求更加规范而引起的，但是具体实在是不知道哪里不规范。因为STM32的例程CUSTOM_HID也能在win7下安装驱动成功。我的程序是通过这个例程修改而来的。

望有经验的大侠给点提示。
