Firewire Webcam

[Christoph Egger]

Hi,

I have an Unibrain Fire-i Webcam.
When I plug it in, then I get this:

fwohci0: BUS reset
fwohci0: node_id=0xc800ffc1, gen=2, CYCLEMASTER mode
ieee1394if0: 2 nodes, maxhop <= 1, cable IRM = 1 (me)
ieee1394if0: bus manager 1 (me)
ieee1394if0: New S400 device ID:08144361026315ce
sbp0 at ieee1394if0: SBP-2/SCSI over IEEE1394
NULL management address

# fwctl
2 devices (info_len=2)
node EUI64 status
1 00-24-1b-00-d7-28-9d-00 0
0 08-14-43-61-02-63-15-ce 1

According to sbp(4) manpage, it is supposed to
attach on DV cams but not on webcams.

Maybe, it is a specification. ;-)

And, I think that software that operates it is necessary for IIDC 1394.
The library might be also necessary. like libdc1394 of Linux.

(Sorry for the necro-posting; found this way deep in my mailbox after looking
for Paul's messages on the latest SDMMC driver)

FWIW, my Canon DV camcorder fails with that same NULL management address
message, so it seems to be generic to our 1394 stack, or require extra
software as Kiyohara-san suggests.
