The story:

The coolscan belongs to my friend.  He's in his 80's, can't walk.  He was a professional photographer and also did photo-art and worked on the local-newspaper as the camera-guy.  He got hit by a truck and his legs don't function anymore.  He had a win98 system somewhere in his house the nikon coolscan was connected to, but I haven't found it yet.  I offered to help him get the coolscan working again so he would be able to scan his film and resume his art and sell his pictures again.  Because all he gets to live on is SSI and medicare and I can't afford to support him.

I found out yesterday that the firewire hardware needed to adapt to my laptop doesn't exist anymore and the intel-code to support it only exists in generation 11 and older.  My laptop is a gen 10 and his laptop is one year older than mine.  I live on SSI too, so I can't buy much to help him with.  I've got a Intel 6gen small form factor Dell computer a pci-board would fit into that's just consuming space.  The board won't arrive till next week.  I was never an Apple guy although I do know they used BSD for an OS. Would the Nikon be more likely to work if I put a BSD OS on a computer?

The poor results with the coolscan3 response tells me it's the cable (I bought two from different vendors) or the nikon coolscan itself.  There's a vague burnt electronics smell emanating from the nikon but I didn't find any damage upon inspection.  There's a voltage divider power-load in the power-supply, the smell seems to be from there so I'm thinking it's ok.

I really appreciate your assistance/advice in this.

    I see the files: coolscan2.conf, coolscan3.conf and coolscan.conf
    in my
    sane directory.  I have a Nikon Super Coolscan 4000 ED connected
    to my
    Dell Latitude 5410.  When I put "scanimage -L" into my terminal I
    get :
    ('v4l:/dev/video0' is a Noname Integrated_Webcam_HD: Integrate

    device) for a response.  I think this is the laptop's camera, not
    the Nikon.


According to the coolscan3 manpage, it is said to support this device through firewire.
I don't know much about firewire support in SANE, but you could try this:

SANE_DEBUG_COOLSCAN3=128 scanimage -L

...and let us see the output.

Cheers,
