    There are some color improvements for some models and a few general
    improvements for others. But it now fails with a few models.

    Not that much, perhaps USB autodetection, but it may change in the
    futur, and it should be included in sane so people don't have to
    retrieve it anymore.

    You can try to replace PRISA620S by SNAPSCAN600 in your model
    description in snapscan.h. It may (or not) improve things. Or even try
    SNAPSCAN300 if the other doesn't work.
