Would be important to know if only skanlite is broken
or if scanning is broken on a lower level.

So please try as root:
zypper in xsane yast2-scanner
yast2 scanner
xsane

Confirmed.
It happens with everything.
I downgraded *just* the sane-backends rpm from openSUSE 13.1 and everything works as it should once more.

According to comment#1 "idVendor=04a9, idProduct=1909" and
http://www.sane-project.org/cgi-bin/driver.pl?manu=&model=&bus=any&v=04a9&p=1909
you have a USB scanner CanoScan LiDE 110 and you use the genesys driver
from the sane-backends RPM.

Caution:
When a scanner makes bad-sounding noises the usual reason is that
the scanner's internal moving parts "do bad things" which means
the scanner hardware could get damaged.

It seems this is the same issue:
https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1184699

Regarding the genesys driver we also have bug#905034 (different symptoms)
but there it also had worked on a 13.1 system.

I do not have a scanner that uses the genesys driver so that I
cannot reproduce anything here.
My scanner usees the plustek driver that works for me.

We (i.e. openSUSE) distribute sane-backends from the SANE project
but we do not develop scanner drivers. In case of issues with
scanner drivers from  sane-backends, you should report them
directly to the driver authors at the SANE project via
http://www.sane-project.org/bugs.html
so that there is a direct communication between you
and the upstream authors.

According to
https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1184699/comments/22
it seems it is fixed in a recent development snapshot at SANE upstream.

I made sane-backends version git20150108 RPMs an unstable
development source only for testing, without any guarantee
or warranty, and without any support in my openSUSE build service
home project "home:jsmeix".

Please read
https://build.opensuse.org/project/show?project=home:jsmeix

You can get the packages in the "home:jsmeix" project
for example for openSUSE 13.2 from this direct URL
http://download.opensuse.org/repositories/home:/jsmeix/openSUSE_13.2/

When you like to upgrade an installed sane-backends 1.0.23 or 1.0.24
to sane-backends development version git20150108 you need to install
version git20150108 with plain rpm using "--force" e.g. like
# rpm -Uhv --force sane-backends-git20150108-2.1.x86_64.rpm
because for rpm the version number git2015010 is lower than
the installed version number 1.0.23 or 1.0.24.

For my scanner that uses the plustek driver sane-backends development
version git20150108 still works for me.

Perhaps you are a venturous openSUSE user who likes to try out
if sane-backends development version git20150108 works for you?

Again note that when a scanner makes bad-sounding noises
it means that the scanner hardware could get damaged.

If you like to try it out nevertheless, please report
whether or not it works for you.

Many thanks in advance for testing it and for your feedback!

I gave it a try -- no luck.
The rpm from 13.1 works perfectly.

Can you perhaps try building a new rpm with the genesys sources from whatever was in 13.1?

Using git bisect, I narrowed it down:


The first bad commit could be any of:

<fin>

I couldn't test the last *four* due to linking errors (not my fault).

I do not have a scanner that uses the genesys driver
so that I cannot do anything here (in particular
I cannot help debugging it because for my scanner it works).

We (i.e. openSUSE) distribute sane-backends from the SANE project
but we do not develop scanner drivers.
In particular I don't have any knowledge about the genesys driver.

Please report it directly to the driver authors at the SANE project
http://www.sane-project.org
so that there is a direct communication between you
and the upstream authors.

The best way is to report it on the sane-devel mailing list so that
the upstream authors plus interested users can notice the issue, see
http://www.sane-project.org/mailing-lists.html

Regarding "Error during device I/O", see
https://bugzilla.opensuse.org/show_bug.cgi?id=905034#c16

Recently there have been various postings on the the sane-devel mailing list
regarding USB I/O issues in particular with USB 3.0 ("SuperSpeed"),
see the "sane to work with USB 3.0" mail thread on
http://lists.alioth.debian.org/pipermail/sane-devel/2014-November/thread.html
http://lists.alioth.debian.org/pipermail/sane-devel/2014-December/thread.html

Regarding issues with higher speed USB see also
https://en.opensuse.org/SDB:Configuring_Scanners#USB_Speed

Only a blind guess:
Perhaps the root cause is not the genesys driver but something
USB related on a lower level (perhaps even in the kernel)
that is somehow triggered by the genesys driver?
When it works with sane-backends-1.0.23 it indicates that
the issue can be at least avoided in the sane-backends software
(even if the actual root cause is not in sane-backends).

I still see the problem on 42.2 with a LiDE 200. Since there's
already lots of useful links in here I'll add my info too. I see the
device IO error if the "cold" scanner is plugged into 42.2. If
however the scanner was used on 13.2 before (same sane-backends
version!) the scanner makes that grinding noise. So I guess the
initialization part of the genesys driver does something that
doesn't work on newer kernels. I also got see the following errors
in 13.2's dmesg, maybe that can give a hint?

Latest git version of sane-backends doesn't work either.

Not completely fixed, just re-tested.
