Hi John,

Sorry it's taken so long for me to respond, but this sounds like the
same problem I had.

After the modprobe, I did the following:

jtait at sixtymilesmile:~$ lsmod | grep raw1394
raw1394                25330  0
ieee1394               94771  2 raw1394,ohci1394

By default, the raw1394 device has very restrictive permissions, because
it can conceivably by misused.  It gives you complete and unrestricted
to the IEEE1394 bus, so exercise extreme caution.  Following the
modprobe command I get:

jtait at sixtymilesmile:~$ ls -l /dev/raw1394
crw-rw---- 1 root root 171, 0 2010-08-25 22:16 /dev/raw1394

My usual workaround is to add myself to the disk group:

jtait at sixtymilesmile:~$ sudo adduser jtait disk
Adding user `jtait' to group `disk' ...
Adding user jtait to group disk

Log out and back in for the new group membership to take effect, then
change the ownership of /dev/raw1394:

jtait at sixtymilesmile:~$ sudo chown .disk /dev/raw1394
jtait at sixtymilesmile:~$ ls -l /dev/raw1394
crw-rw---- 1 root disk 171, 0 2010-08-25 22:16 /dev/raw1394

Kino is usually happy with this arrangement.  It is possible to set up
udev rules to the desired permissions, but to be honest I use the DV
camera infrequently enough that it hasn't been worth looking into it.

Hope that helps!
