It should be of a type that shows exactly what it is. Is it a hyper_v device that talks on the bus? Or is it a "platform" device that controls all of the devices on the bus, and as such should be the "root" device of the bus tree? confused, greg k-h _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
