    well nice looking device not much info on the manufactures website
    www.veho-uk.com but they say its twain compliant so you may be lucky and
    it be a recognised by the system, lot of money to waste if its not
    though, waste of time talking to the "Tech support" in novatec there a
    bunch of doze users, basically they look on a tick sheet and if its not
    there they don't have a clue.

    There is an email you could try should you need additional assistance
    then please email their technical support at

    best of luck

    Their FAQ suggests they are are working on a driver for OSX ("coming soon"),
    so maybe they'll work on one for Linux too? Why don't you contact them and
    tell them your buying decision is based on their support for Linux?

  4. FWIW, I have a Minolta Diimage Scan Dual slide scanner. Its Twain
    compliant, though I've only driven it through its own Windows software.
    I did find that it's listed in the SANE database as supported but I
    haven't got any further than that towards running it with The Gimp.

  5. One of these arrived here yesterday, though it will be not available
    for testing until next week ;-) but then I'll try it with a couple of
    distros including Ubuntu (gutsy) so if you can wait until then..!

    Is it supported by Vuescan (not free but good and cheap)? Vuescan works
    under both linux and windows.

    Only £64 at Scan:
    http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=603579

    Hmm. Review here:
    http://www.computerbuyer.co.uk/buyer/reviews/120578/veho-vfs001.html
    Seems cheap and cheerful but not brilliant.

    FAQ here: http://www.veho-uk.com/index.php?f=DisplayFAQs&t=FAQs claims
    TWAIN support. No idea whether that works under linux.

    I don't understand the product description:

    If it's 3600dpi and a 35mm neg is about one and a half square inches then
    it should scan 3600x3600x1.5 pixels, or about 19.4MPix -- yet it claims to
    be only a 5Mpix scanner (despite claiming to be able to interpolate to
    7200dpi). Something here is not quite right.

    I'm also a bit concerned about that claim that it works with USB2 but not
    USB1.1. USB1.1 compatibility is part of the USB2 spec, so if it's a
    competent implementation of USB2 it should work with either.

    I'm not sure that I'd trust it to work at all well.

    I really wish I'd bought a Minolta film scanner when Morgans had some
    cheap a year or so ago!

    [alt.os.linux.ubuntu trimmed from newsgroups list as my ISP doesn't carry
    it]

    Cheers,

    Isn't TWAIN support just a software API, so has no bearing on whether
    it works under different OSes or not, but only if it will co-operate
    in some way with other apps?
    It might just be a cock-up but it also might be hardware that is told
    what to do by the computer and then just forges ahead, putting data
    into a ring buffer that the computer has to read out of quickly before
    it gets overwritten. Obviously this is idle speculation though.

    I have a flatbed scanner that the computer semi-controls, it says
    "scan" and off the scanner goes, scanning in a 20 page document even
    if you click "cancel" halfway through page 1 and/or unplug the USB
    cable. The only way to make it stop is to turn it off at the wall, or
    take all the pages out of the in tray and wait for it to finish the
    one it's on.
    I've got one and it worked with vuescan quite well, better than the
    supplied windows software. Might dig it out again once I get my rooms
    decorated, lots of slide film kicking around unscanned.

    TWAIN is a protocol ... and by extension an API to provide programmatic
    access to that protocol .. for talking to imaging devices (e.g. over USB).

    However, not every device that supports the protocol supports it fully or
    in exactly the same way as any other, and different implementations of the
    client side of TWAIN have greater or lesser expectations as to how any
    given device will behave.

    So, yes, TWAIN support ought to just mean that the scanner will work with
    any TWAIN-aware application on any system -- but in practice it's not so
    simple.

    Given the other statements made by Veho about their device I'm not inclined
    to suppose that it will be one of the better-behaved TWAIN devices!

    Something being a protocol doesn't mean it is by extension an API.
    You can have a protocol without a standardised API, the protocol
    defines what has to happen on for example a communications link while
    an implementation of that protocol might have a specific API but a
    different implementation of that same protocol can have a completely
    different API.

    Coming from the other end, you can have a standard API that can then
    be implemented in whatever manner the developer sees fit, and I think
    this is what TWAIN is, you still need a driver to present a TWAIN
    interface to the application software so a "scanner" is not TWAIN
    compliant, it's driver is. This means a scanner's billed TWAIN
    compliancy doesn't mean it will work on any other OS other than the
    one for which the TWAIN-compliant driver has been written for.

    I've just had a quick flick through the TWAIN specification for 1.9
    (not all 556 pages I hasten to add!) and yes indeed it's just a
    software-to-software API, device drivers still need to be written for
    each scanner so TWAIN does not have any part in the manner in which
    the computer itself communicates with the scanner.
    This will only be true if the scanner has a TWAIN-compliant *driver*.
    My HP scanner has two drivers, one proprietary one that works only
    with their dreadful scanning software, and another poorly-written
    TWAIN compliant driver that will work badly with any TWAIN software
    such as Photoshop. There are no linux drivers in stable form for the
    scanner, although CVS versions of SANE apparently have it (it's a
    5590).

    Um ... you may be right. I had the idea that the TWAIN defined the
    communications protocol between the computer and the imaging device and
    the API was just a handy set of functions that managed a conversation
    using that protocol -- the Wikipedia definition of TWAIN /seems/ to
    support this (I did check).
    Yes, I had a look at the specs on twain.org, too. It seems that -- as
    you say -- TWAIN applies to the API and that a "TWAIN driver" is needed
    to handle communications with any given device.

    Looks like I may have got that wrong (and Wikipedia is misleading).

    So, the Veho scanner's ability to support TWAIN depends on the
    competence of that TWAIN driver, and the ability to use that scanner as
    a TWAIN device under linux depends on the availability of that driver
    for linux.


    Cheers,
    Daniel.

  15. Not looking good, I get

    usb 4-8: new high speed USB device using ehci_hcd and address 5
    usb 4-8: configuration #1 chosen from 1 choice

    under mandriva (2007) and something similar with ubuntu gutsy and that's about it
    xsane gives me no devices detected, anything else I could try?

    I see that the manual suggests
    'for supper in the UK email [email protected]'
    :)

    Works ok with XP, will put a scan somewhere net accessible if reqd

    Do you have the libsane-extras package installed?
    I emailed [email protected] about Linux support, but didn't get a reply (or any
    supper).

    Thanks for trying, looks like that scanner is off the list :-(.

    What's the quality like?

  17. [on trying the VEHO with flavours of Linux]
    I do - under ubuntu - this is on a HP laptop but I doubt if that
    aspect has much of an effect

    Let us know if you do hear anything back from support!
    Not bad, some of the skies are a bit iffy (or the originals!) but maybe that's me being
    impatient, I've tagged the scans under flickr here

    http://www.flickr.com/photos/[email protected]/tags/slidescan/

    I see that today's Guardian is advertising something incredibly like it for 99.99 ;-)

    Will do - but I'm not hopeful.
    They look quite good to me.

    Thanks once again, Robert.

  19. Thank you! I obviously chose ones which were on the better side - that
    was a bit silly of me - I've now added a few less good ones, though
    some of these - particularly the dawn one - were a bit challenging

    When scanning with it you have to watch it carefully as it keeps on
    altering the colour mix (or whatever) and sometimes it goes too far
    and gets too dark or sometimes washed out!

    Reply to my e-mail to technical at veho-uk.com, enquiring if there are
    Linux drivers available:

    There is no official veho driver for this operating system.

    Thank you for your support in veho...

    Hi,

    I am considering purchasing a VFS-001 Film Scanner. I don't run windows,
    could you tell me if it works with Ubuntu Linux, please?

    Thank you.
