USB common class generic parent driver (usbccgp.sys) will
handle the enumeration for your composite device. If the interface
have windows built-in drivers (like HID, USB mass storage, etc),
they will work automatically. For the other interface, you need
the inf file to point to that interface (eg: USB\VID_0403&PID_6001&MI_00
means Interface 0 of device VID_0403&PID_6001;
VID_0403&PID_6001&MI_01 will mean the Interface 1).

What is the error message you get under Windows for your
USB composite device? It should have three entries under
Device Manager. One is USB Composite device (for the whole device),
one is the USB mass storage device (for the USB mass storage
interface) and the USB RNDIS device (for the RNDIS interface).
