I am a member of the Linux 1394 team, and I have been improving hotplug
capabilities of various ieee1394 modules. Below is my patch to the agent
script. For two different classes of video camera, some applications
require 2 modules: one for the control protocol and another for the
streaming video. Therefore, you see I removed that break. Also, I added
support for a module-specific script directory. This is especially
useful for sbp2 to invoke the popular rescan-scsi-bus.sh script, 
/etc/hotplug/ieee1394/sbp2 script:

#!/bin/bash
if [ "${ACTION}" = "add" ]; then
	. rescan-scsi-bus.sh
else
	. rescan-scsi-bus.sh -r
fi

Similarly, a dv1394 script could launch Kino on add, and a video1394
script could launch Coriander on add.
