| Say Y here if you want to plug devices into your computer while |

| |
| One well known example of this is PCMCIA- or PC-cards, credit-card |

| plugged into slots found on all modern laptop computers. Another |
| example, used on modern desktops as well as laptops, is USB. |
| |
| Enable HOTPLUG and KMOD, and build a modular kernel. Get agent |
| software (at <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. |
