Comment 6 for bug 779680

I have the same problem. It seems it's a kernel problem because (as I understand) dvgrab should work with the new firewire stack too. But that new stack seems to be broken at least for some people. You can find several forums post in the net about it.

dmesg shows this:

[ 430.890270] firewire_ohci: Added fw-ohci device 0000:03:0e.0, OHCI v1.10, 4 IR + 8 IT contexts, quirks 0x2
[ 431.390397] firewire_core: created device fw0: GUID 00df399600001d7d, S400
[ 1055.715686] firewire_core: phy config: card 0, new root=ffc1, gap_count=5
[ 1055.715928] firewire_core: skipped bus generations, destroying all nodes
[ 1056.210074] firewire_core: giving up on config rom for node id ffc0
[ 1056.210137] firewire_core: rediscovered device fw0

That means that /dev/fw1 is not created when I plug in my camera. Therefore dvgrab can't find it.

I tried oneiric kernel 3.0.0 and Ihave the same problem (with natty)
