This report may come off slightly messy, since I'm using a two non-portage ebuilds, and its my first time reporting. I'm using: iscan-2.20.0-r1.ebuild from bug 248898 (Portage iscan appears broken) iscan-plugin-gt-x750-2.1.0.ebuild from bug 277117 The problem is that the scanner misreports its DPI lower then what it actually supports. There is an older patch [1] avalable for the epkowa driver, but it won't work with the newer version of iscan. Perhaps somebody could take a few seconds and write up a hackish patch as a temporary fix? [1] -- http://www.patrickmin.com/linux/tip.php?name=epson4490 Reproducible: Always Steps to Reproduce: 1.

This is kind of a tough one... the code from the patch doesn't appear in any form in the recent releases, so that hack can't be forward ported. It wasn't obvious how to do a new hack either, so not having a scanner here to test with, my chances of getting it right are pretty slim. So, what were the problems you ran into with the ebuild in the tree? I think the package maintainers will be more interested in trying to get the official ebuild working properly than hacking up an older version.
I figured as much, that without a scanner fixing this bug would be close to impossible. With any amount of luck, an experienced dev who ownes this scanner might eventually come across this... As for the ebuild in portage, I just realized that I think I only tried 2.11.0 from the tree (which threw an error), and missed the newer 2.21.0 version in the tree. Currently I'm using 2.20.0-r1. When I have a second, I'll try the newer version tomorrow and see if it works any better.
Yes, please try the newest 2.21 ebuild in the tree. I am not sure it will solve your problem (probably won't), but anyway it's the only version we can officially support.
Hi guys. I updated to 2.21 but as expected the problem persists. (Also, I'm still using media-gfx/iscan-plugin-gt-x750-2.1.0 from the above ebuild, because there is no copy in the tree.)
version 2.25.0 is in portage. please test. and yes, the binary modules are missing at all right now. We will eventually (re)add them. But I don't know when, because it's a little bit complicated. I will close that bug now. feel free to reopen, if your problem still exists.
