Hi. Up to date Sid, 2.6.22

The dvgrab program is trying to access /dev/raw1394, to pull data from
my video camera (as if that wasn't implicit already).

Funny thing is, /dev/raw1394 doesn't exist.

I'm accustomed to having to fix permissions on it every once in a
while, but it hasn't simply "not existed" before.

lsmod shows the following modules:
- ------------------
# lsmod | grep firewire
firewire_sbp2 12100 0
scsi_mod 136620 5
sr_mod,firewire_sbp2,sd_mod,usb_storage,libata
firewire_ohci 16416 0
firewire_core 38784 2 firewire_sbp2,firewire_ohci
crc_itu_t 2144 1 firewire_core
- ------------------

According to the 2.6.22 release notes, these are the modules
that "should" be loading, so it seems to be working ok at that level.

Google search results include lots of dmesg outputs with "/dev/raw1394
device initialized" in them, but there is no such line in my dmesg.

The following comes up when I put the camera online:
- --------------------
firewire_core: phy config: card 0, new root=ffc1, gap_count=5
firewire_core: phy config: card 0, new root=ffc1, gap_count=5
firewire_core: created new fw device fw1 (0 config rom retries)
- --------------------
so the kernel drivers are seeing the hardware, anyway.

Suggestions?

Curt-

modprobe raw1394

(This module does not seem to get loaded automatically for all hardware.
I have no idea why that is or how to fix that.)
