SANE does not work anymore with Epson Perfection 1650. Used to work perfectly.

[Dan Kegel]

On my plain vanilla ubuntu 13.04 system, with an Epson Perfection 1650 scanner plugged in,
clicking 'Scan' in xsane, or running scanimage, yielded a short scan run and the message
'[epson2] e2_ext_read: cancel request received' on stderr.

This turns out to be caused by the commit

    epson2: improved error detection

as guessed by a comment in the related Debian bug report
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=597922#127
which also had a spot-on suggestion for how to fix it.
I've attached the draft patch to
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=597922#215

There is also an upstream bug report,
https://alioth.debian.org/tracker/?group_id=30186&atid=410366&func=detail&aid=312793
but I have not been able to comment there (alioth's login system defeated me).
That upstream bug report also has a simple workaround (edit /etc/sane.d/dll.conf to
uncomment epson and comment epson2), but a real fix would be nice.

So, assuming no upstream release before 13.10, how about adding my patch?
I'd be happy to submit it in a more ubuntu-friendly form.

Given that beta1 is in three days, I suppose this is a long shot, but:
I'm attaching the commit and checking the 'patch' checkbox...

The attachment "Cherrypicked fix from upstream" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

[John Paul Adrian Glaubitz (glaubitz)]

I uploaded sane-backends 1.0.24-1.1 to Debian unstable yesterday which contains the commit, I have therefore closed the bug on Debian.

Please wait until Ubuntu has imported 1.0.24-1.1 from Debian or you can ask me for a build for your specific version of Ubuntu for tesing.

I would like to close this bug report as soon as possible.

Please import sane-backends in time for 14.04...

[penalvch (penalvch)]

Dan Kegel, I'm closing this as Xenial+ would have the fix.

If you require a backport to a prior release, please advise.
