Hi rexcze,
probably you must load some modules in order to use your digital camera
If you have the stock Arch kernel try with:

 modprobe firewire-ohci

Re: FIreWIre camera

Ive already loaded ohci1394 raw1394 ieee1394 firewire_ohci firewire_core, but KINO tells me this:

(in czech Selhalo čtení/zápis zařízení /dev/raw1394)
in english something like: I can read/write on device /dev/raw/1394

User who running kino is in group camera.

Re: FIreWIre camera

If you are in the video group all should work correctly
Try to logout and login again

NOTE: The dv1394 driver is unsupported and may be removed in a future Linux release. Use raw1394 instead.

Re: FIreWIre camera

Hi rexcze,
this is not a solution but a workaround:
start the program as root user:

su -c kino

and see if it works correctly
I don't have a digital camera, so my tests are quite limited

Re: FIreWIre camera

If I run Kino as root I have exactly thew same problem.

Re: FIreWIre camera

Sorry to resurrect an old thread, but I'm having an identical problem.  The modules are loaded, the permissions seem right but nobody, including root can access the camera with either ekiga or kino.

with Ekiga, the error I get is

(dc1394_control.c) Couldn't raw1394_set_port!

and with kino:

WARNING: raw1394 module not loaded or failure to read/write /dev/raw1394!

dvgrab just says that no camera exists.

A few miscellani for reference:

$ lsmod | grep 1394
dv1394                 16988  0 
raw1394                25340  0 
$ lsmod | grep fire
firewire_ohci          15360  0 
firewire_core          36032  1 firewire_ohci
crc_itu_t               2304  1 firewire_core

$ ls -la /dev/raw1394
crw-rw-rw- 1 root video 171, 0 2007-10-03 01:04 /dev/raw1394

Clearly, I've already twiddled with the permissions to no avail.  I had this darn camera working once under another distro, so I'm sure that it's not my device.

Any advice for where to start?

Re: FIreWIre camera

I don't have any fire-wire device, so I actually have no idea about ieee1394 whatsoever, but I thought dv1394 and raw1394 were not meant to be used together. Does it work if you only have raw1394 loaded (so modprobe -r  dv1394 raw1394; modprobe raw1394)?
