Sorry but what do you mean by the above? As per the previous discussions, it seems that a registry entry hack (for Vista and Windows 7) is needed. http://msdn.microsoft.com/en-us/library/ff538059%28VS.85%29.aspx

It seems to me your inf file forces the USB Generic Parent Driver (for USB Composite Device) to load. But for which configuration? I do not have any device to test myself. But I tend to guess it will still be the first configuration (either RNDIS or CDC ECM).
I did see something similar for WMCDC. http://msdn.microsoft.com/en-us/library/ff538833%28VS.85%29.aspx http://msdn.microsoft.com/en-us/library/ff537100%28v=VS.85%29.aspx
