Re: Anyone using dvgrab successfully in opensuse 11.0/11.1?

After unloading driver, dmesg|grep 1394 gives

ohci1394 0000:02:0f.2: PCI INT A -> Link[LNKD] -> GSI 10 (level, low) -> IRQ 
10
ohci1394: fw-host0: OHCI-1394 1.0 (PCI): IRQ=[10]  MMIO=[f6ffd800-f6ffdfff]

ieee1394: Node removed: ID:BUS[0-00:1023]  GUID[434fc000248c8821]

After plugin/switch on the camera and modprobe ohci1394,
dmesg|grep 1394 gives

and grep . /sys/bus/{ieee1394,firewire}/devices/*/* generates

I see that both node_count and selfid_count is still 1.
