perhaps the code size is arguable as to whether it really matters. the reason we want it is that we have a USB host controller that will not work with USB hubs, so we want to make sure the system does not attempt such things. (yes, such a USB host controller is retarded, but the decision was out of our hands.) -mike -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
