-        bool "Support for hot-pluggable devices"
-        help
-          Say Y here if you want to plug devices into your computer while
-          the system is running, and be able to use them quickly.  In many
-          cases, the devices can likewise be unplugged at any time too.
-
-          One well known example of this is PCMCIA- or PC-cards, credit-card
-          size devices such as network cards, modems or hard drives which are
-          plugged into slots found on all modern laptop computers.  Another
-          example, used on modern desktops as well as laptops, is USB.
-
-          Enable HOTPLUG and build a modular kernel.  Get agent software
-          (from <http://linux-hotplug.sourceforge.net/>) and install it.
-          Then your kernel will automatically call out to a user mode "policy
-          agent" (/sbin/hotplug) to load modules and set up software needed
-          to use devices as you hotplug them.
