Then, manually loaded via 'modprobe raw1394':

I don't get what this is about. Who denies what?
It just says denied, but selinux is set permissive, so thats just a
report of what would be denied if it was fully enabled.
SELinux is in permissive mode, and /dev/raw1394 has perms of:
[root@diablo ~]# ls -l /dev/raw1394
crw-rw-rw- 1 root root 171, 0 Oct 16 11:50 /dev/raw1394
As I had given up, the camera is packed away, but I'll get it out and
connect it again for grins:
And no further messages were logged when I plugged it in and turned it on.
There should be something like "ieee1394: Node added: ID:BUS[0-00:1023]
GUID..." and that the host changed from 0-00 to 1-00 at kern.debug level.
Never happens.
kino-0.8 receives video from it in real time and is doing so right now,
and can capture it to file, and then play/edit that file, or could
saturday when I last tried it. I ASSume that kino-0.9.2 could also
play/edit that file, but have not verified that by reinstalling 0.9.2.
...
Did you run FC2 as 32bit environment on 32bit kernel?
Yes, and kino-0.7.5 died with kernel changes in the ieee1394 code
someplace at about 2.6.9 IIRC.
...
before someone just had to rewrite the 1394 stuff again?
The 1394 kernel drivers are not being rewritten.
I was told it was a total rewrite of bad code when I complained about a
year ago. My reply at the time was that it worked, and I don't often
fix things that are working. I'm getting lazy in my dotage I guess.
I don't remember what was changed at that time. Maybe that was the
addition of the new isochronous interface that I mentioned. The old one
was (is?) still there but maybe there were interactions... However this
is not related to the inability to issue AV/C commands, which are issued
asynchronously. I think though that your kino 0.8.x package is
configured to work isochronously via video1394(?)
Its showing raw1394, the other choice is dvgrab, which doesn't...
but asynchronously via
raw1394, and the kino 0.9.x package to do both via raw1394. But don't
take my word on it, I keep mistaking one interface for another. I never
used video cameras on FireWire myself.
As for 1394commander or gscanbus, I have not managed to find rpms of
those in any of the repos yumex or SPM shows me. They apparently are
not part of the FC5 tree. I'd love to see what those 2 might have to
say about the system. The only thing I do have is dvcont, which reports
this:
[root@diablo ~]# dvcont dev 0 play
Could not find any AV/C devices on the 1394 bus.
The camera is still plugged in and powered up.
Anything under /sys/bus/ieee1394/devices?
[root@diablo ~]# ls -R /sys/bus/ieee1394/devices
/sys/bus/ieee1394/devices:
08004601044684e4 08004601044684e4-0 623f0200cbe5407d
623f0200cbe5407d-0 fw-host0
and:
[root@diablo ~]# ls -l /sys/bus/ieee1394/devices/fw-host0
lrwxrwxrwx 1 root root 0 Oct 16 11:16 /sys/bus/ieee1394/devices/fw-host0

It might be not too difficult to compile 1394commander since it doesn't
have many library dependencies; just libraw1394 (probably as -devel
package) and optionally readline. Gscanbus would show a bit more about
attached devices without resorting to magic commands but it is a bit
harder to compile, as a GUI program.
I'll put in the devel stuff and give it a shot. And let the lists know.
I did find, with googles help, some rpms of 1394commander and gscanbus,
but they don't work here.
gscanbus bus displays two icons, one for the device (ohci1394) running
at 400megabaud, and the camera running at 100 megabaud. Clicking on
either icon locks it, but it does respond to a ctl+c in the shell the
launched it.
And 1394commander has problems with my readline library I think:
[root@diablo src]# 1394commander
1394commander: symbol lookup error: /usr/lib/libreadline.so.5:
I believe its way too long in the tooth for modern 1394 snooping as its
3 years old or more.
I tried to build the src rpm of gscanbus, but it autoedits gscanbus.c,
wrapping long lines which then fail to compile due to missing final " in
a 2+ line text argument. Its there, but the compiler apparently expects
to see the ending " on the same line as opposed to 2-3 lines below.
Thanks, Stefan
