Firewire, udev, no /dev/raw1394...why?

Hi forum,
I've googled and looked for hours...so finally came here.
The camera is Panasonic PV-DV51D. It worked under FC2.
The problem: no /dev/raw1394 entry in dev directory.
dmesg:
ieee1394: Current remote IRM is not 1394a-2000 compliant, resetting...
ieee1394: Node resumed: ID:BUS[0-00:1023] GUID[00804580b0c981eb]
ieee1394: Node changed: 0-00:1023 -> 0-01:1023


Interestingly the device gets initialized in the log file:
[root@localhost ~]# cat /var/log/messages | grep ieee
Sep 23 18:15:44 localhost ieee1394.agent[4547]: ... no drivers for IEEE1394 product 0x/0x/0x
Sep 23 18:15:44 localhost ieee1394.agent[4550]: ... no drivers for IEEE1394 product 0x/0x/0x
Sep 23 18:15:44 localhost kernel: ieee1394: raw1394: /dev/raw1394 device initialized


[root@localhost ~]# lspci | grep Fire
00:09.2 FireWire (IEEE 1394): Creative Labs SB Audigy FireWire Port


Udevinfo reports that there is something in /sys filesystem:
[root@localhost ~]# udevinfo -a -p /sys/devices/pci0000\:00/0000\:00\:09.2/
[...]
looking at class device '/sys/devices/pci0000:00/0000:00:09.2':
SYSFS{class}="0x0c0010"
SYSFS{detach_state}="0"
SYSFS{device}="0x4001"
SYSFS{irq}="10"
SYSFS{subsystem_device}="0x0010"
SYSFS{subsystem_vendor}="0x1102"
SYSFS{vendor}="0x1102"



I tried to learn the rule making technics and ended up like so:

[root@localhost ~]# cat /etc/udev/rules.d/10-udev.rules

SYSFS{class}="0x0c0010", SYSFS{device}="0x4001", NAME="raw1394"


I'v tried KERNEL="ieee1394" and KERNEL="raw1394" in place of SYSFS{class} but to no avail.

But still there is no /dev/raw1394 device node:
[root@localhost ~]# ls /dev/raw*
ls: /dev/raw*: No such file or directory




I'd be happy to get hints on how to fix it.

Do you happen to have the firewire kernel module loaded? On my system in /etc/modprobe.conf, I have this line, alias ieee1394-controller ohci1394 and firewire starts up when the system boots. I also have /dev/raw1394. Now all I need is a firewire device to use my firewire ports. By the way, what kernel version are you using? I believe that they re-enabled firewire support in kernel-2.6.6-1.427. Also, I noticed you said that your Panasonic PV-DV51D worked under FC2. What distro are you running now?

I have the same problem, you can create it by using "mknod -m 666 /dev/raw1394 c 171 0" but you might have to create it everytime you boot.
