The handling of hot-plugging must be done by those drivers which are
handling this piece of hardware. E.g. if you have a USB host controller
driver, this driver will get notifications and can then propagate those
to others. There's currently no driver (infrastructure) which is doing
hot-pluging, AFAIK. L4Linux is an exception but it's probably not
counting here.
