Epson ALCX11NF Scanner I/O error in xsane

[Paul Tap]

Binary package hint: xsane

My Espon ALCX11NF scanner only gives an I/O error when trying to scan (via the network, no USB possible). The scanner (although (still) being reported as an Epson LP A500 on startup of xsane) used to work with 9.04 and 8.10 out of the box.

I tried to get some more info via scanimage( D10 is the 9.10 machine, pepe is a 9.04):

It may be the message shown by scanimage -L already indicating trouble on its way.

Hello,
I have the same problem with Canon Lide 50.
I was using Ubuntu 9.04 and scanner was working. After upgrading to the 9.10 I cannot scan documents anymore :(

I too have a Epson AL-CX11NF that was working find with xsane and gscan2pdf under 9.04. Having done upgrades and fresh installs now to 9.10, both 32-bit and 64-bit, I get the "error during device I/O" error on all of them.

[Pawel Urbanowski (pawel-urbanowski)]

It seems that the only resolution is coming back to the ubuntu 9.04.

[Werner Kuballa (wkuballa)]

I get the same message with an HP OfficeJet 7300 All-in-One. This used to work in 9.04.

I noticed also that I get messages in "daemon.log" on the system (Mars) that has the printer/scanner attached when I run the "scanimage -L".

I confirm with AL-CX11NF (network scanning)

[gmud (gmud)]

@PiK:

> It seems that the only resolution is coming back to the ubuntu 9.04.

Fortunately there is a dirty workaround:

download http://packages.ubuntu.com/jaunty/libsane (jaunty version) and install with
dpkg -i libsane_1.0.19-23ubuntu7_i386.deb

You may lock libsane with synaptics or with preferences of apt until this bug is resolved.

[Pawel Urbanowski (pawel-urbanowski)]

@Gero Mudersbach
Thanks for a workaround.

[Stephan Bgl (boegel)]

@Gero Mudersbach

Workaround works perfectly with Canon LiDE 35. Thanks a lot.

[Guiodic (Guido Iodice) (guido-iodice)]

Downgrading libsane as written by Gero works on Epson AL-CX11NF

[bersyl91 (choppy-free)]

Downgrading doesn't seem to function with Umax AstraSlim SE : the scanner is well recognized but scanimage hangs eternally.

I upload an strace log if this can help.

[bersyl91 (choppy-free)]

Okay, it seems to function now. It's a bit difficult to explain exactly what happened, but here is what I did:

 - Downgrade to jaunty's version of libsane
 - fix definitively permissions of device via udev (cf. infra)
 - Adjust path to firmware (strangely enough, it had changed) in /etc/sane.d/<my_scanner>.conf
 - Upgrade back to current (1.0.20-4ubuntu3) libsane version

Now it's ok.

Concerning the permissions, I created a rule in /lib/udev/rules.d/99-custom.rules:
ATTR{idVendor}=="05d8", ATTR{idProduct}=="4009", MODE="0664", GROUP="saned"
(of course, idVendor and idProduct are those given by the lsusb command and I'm member of the saned group).

[Lucio (lumatemp-nospam)]

Just downgrading does not solve the problem with my CanoScan Lide 50 and I am not able to follow bersyl91 instructions... please help!

[Ralph Corderoy (ralph-inputplus)]

It appears the Canon Lide 50 problem has a patch provided on Debian that fixes the issue. https://alioth.debian.org/tracker/?group_id=30186&atid=410366&func=detail&aid=311691 There's more than one patch. The one claimed to fix things is https://alioth.debian.org/tracker/download.php/30186/410366/311691/3259/sane-always-send-registers.patch

Sure this bug deserves to have an importance decided? Many Lide 50 users, and other scanners by the looks of it, will find 9.10 regresses compared to 9.04.

[larytet (larytet-48904418)]

Confirmed for xsane and Brother MFC-440CN

I would appreciate if more details provided on the bersyl91's workaround

[bersyl91 (choppy-free)]

Downgrading/upgrading
===================

@Lucio: No, downgrading didn't solve the problem for me either.

I had another semi-similar problem (with cups-pdf) and another guy told it solved it by uninstalling/reinstalling.
I had already done that with sane and it didn't solve my problem.

So I tried to dowgrade, and it didn't solve it either.

So I decided to upgrade back and the scanner happened to work.

Firmware
=======

Be careful, though, because it seems that the path where saned searches the firmware had changed.

For me, in the config file /etc/sane.d/artec_eplus48u.conf, I had to fix the line:
 option artecFirmwareFile /usr/share/sane/firmware/Artec48.usb

because the firmware really was located at:
option artecFirmwareFile /usr/share/sane/artec_eplus48u/Artec48.usb

udev rules
========

To have access to the device as a normal user, you have to inform the device manager about the permissions you want to find on your device.

The USB devices are identified by 2 fields : the vendor one and the product one. A lsusb command gives you both with the form XXXX:YYYY (XXX being the vendor one, in my case, 05d8 and YYYY the product one, for me 4009).

I decided to give my scanner the 0664 permissions, so that any memeber of the group "saned" might be able to write commands to the scanner.

@larytet: I'm afraid I can't be more explainful - hope this is good for you

[Ralph Corderoy (ralph-inputplus)]

It seems commit a0ea955e91837156d2112c0ffd12c8afebe86efa fixes the Canon Lide 50 problems according to the Alioth bug I linked to above. Patch viewable: https://svn.pardus.org.tr/pardus/2008/stable/applications/hardware/sane-backends/files/Always-send-registers-before-trying-to-acquire-line.patch

[CA Wills (infocawills)]

As a recent convert this problem would have sent me back to M$. It is only by the help of DLUG members that I've persisted with Linux, please,please sort this out. My Lide 50 worked with 9.04 so why doesn't it in 9.10? It's no good telling people to try this or try that then compile - no good if your new and have very little programming experience.
Error in I/O does not mean a thing - what I/O? where? how?

[Stephan Wüthrich (ubuntu-runway)]

I have the same problem with lide 50. Please fix it soon. Thank you !

[tmschmitz (tmschmitz)]

I have an HP Photosmart C3180. I was having this problem, but "sudo adduser saned lp" fixed it for me. No need to add yourself to any groups, downgrade libsane, or muck around with udev. If your scanner is not an all-in-one, the addition of the udev rule will probably be necessary, but you shouldn't need to add yourself to the sane group, the daemon takes care of that.

[Lucio (lumatemp-nospam)]

I used a workaround for having my Canon Lide 50 work in Karmic, following Cosmin suggestions reported in bug #485551.

The complete downgrade involving BOTH xsane and libsane allowed the scanner to work again, BUT lead to unclean exit in xsane. So I also removed xsane and installed FLEGITA, leaving libsane downgraded to 1.0.19.

Now the scanner seems to work well. I can also use gscan2pdf, but had to change preferences/frontend to libsane-perl.

I think this could do until the libsane 1.0.20 and xsane problem is fixed.

[Pawel Urbanowski (pawel-urbanowski)]

Does this bug exists on Ubuntu 10.04?

[Lucio (lumatemp-nospam)]

The error is no longer present for my CanoScan Lide 50 while running Lucid!

[Guiodic (Guido Iodice) (guido-iodice)]

@pik: yes, libsane on Lucid gives the same I/O error.

[Guiodic (Guido Iodice) (guido-iodice)]

libsane from maverick solves the issue! you can download it from my PPA

https://launchpad.net/~guido-iodice/+archive/guiodiclucid/+packages?field.name_filter=sane-backends&field.status_filter=published&field.series_filter=

or you can add my repo: ppa:guido-iodice/guiodiclucid

[teledyn (garym-teledyn)]

the problem persists with Ubuntu 10.04 UNR using an HP 1315 PSC; I can print and scan from the localhost without problems, and the daemon.log show that my network permissions in saned.conf are "access granted" thus allowing the remote host to connect, but that is immediately followed by the identical log lines reported by others, musb.c:137 unable get_string_descriptor -1: Operation not permitted and on lines 2017, 2022 and 2027, "invalid manufacturer string"

This worked fine in Ubuntu 8.04 and 9:04.

[Fred Saunier (fsaunier)]

Just for the sake of trying - same problem with my AL-CX11NF (network) running Maverick live.

The only workaround I have so far in Lucid is to downgrade to Jaunty's libsane - which is then incompatible with Lucid's Gimp :( One of my computers is still running Jaunty, for the single purpose of being able to scan and gimp easily :((

[Lucio (lumatemp-nospam)]

Not sure if it is the same bug as before, but in Maverick I am again unable to work with my Canoscan Lide 50.
The scanner is recognized, but when starting acquisition it makes high-pitched noises and does not acquire the page.
It works on other PC with Lucid.

[ecanod (acmebike)]

Same problem as Lucio #36.

scanimage -L returns: device `genesys:libusb:001:003' is a Canon LiDE 35/40/50 flatbed scanner

scanimage >image.pnm starts the scanner but the scanner lamp stays at the beginning of its travel, without moving, making those high-pitched noises

scanning using Xsane yields the same result

scanning using Simple Scan moves the lamp, but at double speed, so the resulting image is compressed lenghtwise and the lamp hits the end of the travel, making again (a different type of) noise.

[Fred Saunier (fsaunier)]

I finally got the Epson CX11NF to work properly in Lucid. As it turns out, the problem comes from libsane which doesn't work properly with network devices that have a longer name (eg wireless devices). See bug reference #572246.

A patch for libsane has been issued by Nicolas Valcarcel, and is available on this ppa :
https://launchpad.net/~cgateam/+archive/ppa

Add the ppa to your list, update and upgrade. Libsane will be updated with the patch, and now xsane works just fine. Finally!

[Fred Saunier (fsaunier)]

I have to take back what I stated earlier, unfortunately, for being over-optimistic. The libsane patch allows xsane to load (which is a step forward), but I'm getting I/O errors whenever trying to scan, both from ethernet or wifi.

[Christian Plenagl (christian-plenagl)]

Hi I just tested the patch from Nicolas Valcarcel, but unfortunately I still receive the same error with my Epson Acculaser CX11NF, when scanning over the network with: executing scanimage -d epson2
scanimage: sane_read: Error during device I/O

[Fred Saunier (fsaunier)]

Aha, got it to scan properly, using Guido Iodice's ppa (post #33) : ppa:guido-iodice/guiodiclucid - which has libsane 1.0.22 (natty?)

In Maverick : subscribe to the ppa, and set the distro to lucid (not maverick). Just update libsane. Xsane now works over the network.

In Lucid : subscribe to the ppa. Upgrade libsane and xsane. It now works over the network as well.

Thank you Guido!

[Christian Plenagl (christian-plenagl)]

Yes, thank you Guido,
this is working very nice now.
Would it be possible to add the libsane 1.0.22 as an update to ubuntu lucid?
