This is because the version of Windows they support on these machines also does not support hotplugging these devices. The current code works just fine on hardware that actually supports this kind of functionality, as per the proper specs and requirements for this feature. So why try to go through these gyrations for hardware that is explicitly broken? thanks, greg k-h - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
