I really appreciate your work and was happy that someone fixed this issue at least for the LiDE20, but I could not accept this: "broken several times..." - If the code is broken before a new SANE version will be released, I'd like to have some feedback not any complaints AFTER code-freeze, that's the way the show works. > Honestly, I don't have the time to fix this for the third time....

That's indeed more or less impossible. I own the N670 which should be more or less the same as the LiDE20, but I could not test every single device before a release takes place - I need feedback from others. > I'll put up the last LiDE20 driver (which works: I'm still using it) I > contributed as soon as the machine it's on is on the Net again (just > moved to a new house, IT there is in disarray). So you're still working with SANE-1.0.13? Is 1.0.14 also broken? In the end the differences to 1.0.13 are not that large. I'll submit a patch probably this evening and you're welcome to cross-check. What about the pictures from 1.0.13? Aren't those too dark? As I already said criticism is a good thing, as long as it is constructive! Ciao, Gerhard
