<div>Hi Leon,<br>
<br>
I've attached a bash script that does waht you're trying to
acheive (sort of, you'll need to cut to size...)<br>
<br>
This just watches the list of FW devices as reported, and reports
whether our specific device is available or not.<br>
<br>
It requires one command parameter, the GUID of the device.<br>
<br>
Regards,<br>

I've come up with something that at least triggers a restart
of the camera when it's plugged back in. I'd like to know that
it's gone, but this will have to do for now.<br>

I've done a bit of poking around and have yet to
find a way I can use to detect when a camera drops
out. DVgrab kindly persists (even with
dvsource-firewire + tally light) and fails to carry
on when you replug the camera.<br>
<br>

I thought about using inotify to watch the sys paths,
however it doesn't appear to be able to monitor these
paths. I also pondered watching the syslog, but it
doesn't log anything on disconnect.<br>
<br>
</div>
I imagine there would be a kernel event I could hook
into, but that's a little beyond my current skillset and
available time to figure out.<br>
<br>
</div>
If anyone has some ideas, I'd love to hear them!<br>
