Firewire Problem (SOLVED)

[AS]

Hi Archie,

I have a couple of things. First, I checked the /dev folder and did not find /dev/raw1394 among the list. I assumed it was a file and thought I could just # cp /dev/rawctl /dev/raw1394 and obviously gave me cp: cannot open `/dev/rawctl' for reading: No such device or address.

Sorry, the above is a wrong assumption.
The directory "/dev" (acronyms for devices) contains only the so called "device nodes", that really are "names" created to access hardware devices.
From a practical point of view the things works in the following way:
- hardware is recognized.
- an appropriate module is loaded to properly manage the found device and a device entry is created in /dev.

You need then to check that appropriate module is loaded, try lsmod | grep ieee1394 and if you don't find the appropriate entry
you should try modprobe ieee1394, thus manually loading the modules. (this is very similar to what reported at the beginning of this thread).

Once module is loaded, probably you will find the device node /dev/raw1394.

Of course, all the above is a starting point, later other setting may be needed.

HTH, AS

Hello AS,

Thanks for the explanation. I did had the idea that the folder was a placeholder for devices. And perhaps the reason why I couldn't find the node /dev/raw1394 is that the module wasn't loaded.

[root@arevalo archie]# modprobe raw1394

[root@arevalo archie]# modprobe ieee1394

So I guess I am in trouble! What do I do now?

Hi,

[root@arevalo archie]# modprobe ieee1394
FATAL: Module ieee1394 not found.

sound very strange, module is available and loaded in my installation. May be you are using an old kernel ?
my module is located here:
/lib/modules/2.6.33.7-pclos6.pae/kernel/drivers/ieee1394/ieee1394.ko.gz

try the following command:
find /lib/modules -name ieee1394.ko.gz

Or could it be that you're using the 2.6.37 kernel in testing? ieee1394 has been omitted for the time being (as far as I know).

And that could be it! I'll install another kernel and post the results. Thanks tschommer.
