    I use a Nikon Coolscan III to scan photo negatives. I've
    recently installed XP and bought a driver to match my
    scanner to the new OS. Possibly relevant too is that I also
    recently bought a new Logitech webcam which installed a new
    version of Twain.

    The Coolscan is recognised by XP as a working device, BUT
    when I try to run Photoshop and import from the scanner
    using TWAIN I get an error message saying that it can find
    no active device. I *can* scan my USB flatbed scanner using
    TWAIN and the webcam works just fine.

    I've tried reinstalling the XP driver for the Nikon device,
    but I have a suspicion it may be that the new version of
    Twain is causing the problem. In Windows/Twain there is a
    folder called CALIBRAT with one file called

    Any ideas what to do next?

  2. If it isn't already on, turn on the Windows Image Acquisition service.

    Thanks, but WIA was active (I restarted just to be sure).

  4. These things do not always work properly. WIA is required, but it is a piece
    of shit, and crappy drivers make it worse.

    You will have to try to find an imaging package that will let you select the
    correct driver and device. Once you've done that, you should have no problem
    with other packages, assuming it's what I think it is that is causing the

    Try accessing the _camera_ via the XP scanning/imaging software. If the
    camera takes still pictures, the XP scanning package will let you pull
    stills from it. You're in for a bit of messing around.

    You may have to unplug the camera when you want to scan, as a last resort.

    Unplugging the camera has no effect. Reinstalling Nikon Scan
    2.5 then 3.1.2 has no effect. The Error message says that
    Nikon Scan "could not open Twain source. Make sure there is
    a valid source for your scanner in the twain directory in
    the windows directory"

    Thanks for any help...

    If it is a SCSI device, download the ASPI layer from adaptec.

    Thanks Roy - absolutely right. Now my only problem is that
    the new version of Nikon Scan has lost all of my settings
    and I can't find the control on the interface to reset them!
    Argh! Ah well, at least it's scanning again...

    Well, close....

    But it turned out it needed a new adaptec driver for the
    SCSI interface.
