I use the following in /etc/devd.conf on my laptop to make it DTRT
regardless of whether it's in the docking station (USB keyboard and
mouse), on my lap (PS/2 keyboard and trackpoint), or on my desk at
home (PS/2 keyboard, USB mouse).

attach 0 {
        device-name     "ums[0-9]+";
        action          "/root/bin/usbmouse start $device-name";
};

detach 0 {
        device-name     "ums[0-9]+";
        action          "/root/bin/usbmouse stop $device-name";
};

attach 0 {
        device-name     "ukbd[0-9]+";
        action          "/root/bin/usbkeyboard start $device-name";
};

detach 0 {
        device-name     "ukbd[0-9]+";
        action          "/root/bin/usbkeyboard stop $device-name";
};

The scripts are attached.  Note that usbkeyboard will be confused if
more than one USB keyboard are attached at any one time; my next
project is to make it possible to have multiple keyboards active at
the same time, just like we can have multiple mice active at the same
time.
