some usb_devices fault if usb_suspend enabled

[Clay Weber]

Binary package hint: libsane

In Feisty, using xsane or Kooka, my Canon Lide25 scanner, which uses the plustek backend, does not produce any scanned image, though both gui applications go through the motions (progress dialogs, etc) and produce a black preview. Using the command line 'scanimage' does produce a scan correctly

The scanner works correctly in Edgy.

Hi :-)

I have a Canon LiDE 25 scanner, woking perfectly with sane-backends-1.0.17. After an upgrade to version 1.0.18 (Gentoo
release 1.0.18-r2), the scanner didn't work anymore; other people also experienced problems with other scanners (see
http://forums.gentoo.org/viewtopic-t-506227.html -- German).

sane-find-scanner lists the scanner anyway, but scanimage -L didn't work anymore.

After a downgrade to version 1.0.17, everything works as expected again.

Greetings, Tobias

Reproducible: Always

Steps to Reproduce:

[Phosphan (phosphan)]

I am not sure what I can do about this, but I will check the source differences and sane CVS as soon as I find some time (which is quite a problem at the moment).

About the forums thread:
Sorry, but sane-backends 1.0.18 has been in ~x86 since july 2006 and in x86 since september. Since no developer has all the hardware I have to rely on user feedback. This is the first time I am told about such problems with .18.

[Tobias-leupold (tobias-leupold)]

They just didn't report a bug, as the downgrade worked for them ;-) I don't know if dev-libs/libusb-1.1.11 matters (as reported on the forums), as just downgrading sane-backends worked for me. I also reported this bug on the SANE bugtacker: https://alioth.debian.org/tracker/index.php?func=detail&aid=304426&group_id=30186&atid=410366

[9-newsletter (9-newsletter)]

Hi,

I have another possible solution to the problem:

My LiDE 25 worked again after removing the kernel-option "Device Drivers - USB Support - USB selective suspend/resume and wakeup". The problem appeared with gentoo-sources-2.6.19.

Other versions:
libusb 0.1.12
sane-backends 1.0.18-r2

[barbobot (deadlyh)]

I am also experiencing this problem.

Bus 001 Device 011: ID 04a9:2220 Canon, Inc.
(While it's device ID is well known, I think it's worth note here)

sane-backend uses the plustek driver for this particular scanner.

[yostral (y-o)]

Same here, with a canon lide 30 :

Bus 001 Device 009: ID 04a9:220e Canon, Inc. CanoScan N1240U/LiDE 30

It's recognized, but doesn't work at all. Nothing is previewed and nothing is scanned.

This scanner works perfectly with dapper and edgy.

[echazare (elie-chazarenc)]

Same here, with a canon lide 20 :
Bus 003 Device 002: ID 04a9:220d Canon, Inc. CanoScan N670U/N676U/LiDE 20
It's recognized, but doesn't work at all. Nothing is previewed and nothing is scanned.
This scanner works perfectly with dapper and edgy.

[etx90 (bruno-germain5)]

Same problem with a Canon Canoscan N656U.

This scanner : works fine with MS Windows
                       makes a lot of noise and does not scan anything with Edgy
                       seems to be recognized with Feisty (herd5), but nothing is previewed nor scanned.

I'm using Xsane under Edubuntu and Omnipage under XP.

[Fabio Marzocca (thesaltydog)]

I confirm this bug in Feisty (xsane was working perfectly with all previous ubuntu versions).

Bus 001 Device 002: ID 04a9:220e Canon, Inc. CanoScan N1240U/LiDE 30

[lebouvier (seb-video)]

i confirm this bug too in feisty. i've got a Canon lide 30 who works perfectly under dapper and edgy but since Feisty it doesn't work at all.

[Emanuel Goscinski (emu--deactivatedaccount)]

Same here with a canon Lide25 and plustek backend.
There appears no errors so that all seems ok but the scanner doesnt scan and a black picture appears in the end.

[max63 (max-maxbase)]

Same for me with a LIDE25 too, the scanner doesn't work just scan a black page.

[Lemmit Kaplinski (lemmit)]

Same here with Lide 25.

Additionally the scanner was not recognized by udev and I had to add the following to /etc/udev/rules.d/45-libsane.rules:
# Canon CanoScan N670U/N676U/LiDE20
SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="2220", MODE="664", GROUP="scanner"

[Thom Pischke (thom-pischke)]

Same here. Canoscan n1240u. Worked fine in Edgy. In feisty, it pretends to work, but does not actually scan, just produces a black page.

scanimage via command does work however.

[Clay Weber (claydoh)]

I wonder if it is a kernel/udev/hal issue as it seems that the libsane version is the same in Edgy and Feisty

http://bugs.gentoo.org/show_bug.cgi?id=165315#c3

[Thom Pischke (thom-pischke)]

Also tried with gnomescan. Exact same behavior. It pretends to scan, with a progress bar and everything, but the scanner itself doesn't even make a peep.

Booted windows and made the scan with no problem, so no issue with the scanner.

[Clay Weber (claydoh)]

From the gentoo bug listed above
http://bugs.gentoo.org/show_bug.cgi?id=165315#c3
I compiled a kernel with the 'USB selective suspend/resume and wakeup' disabled, and it does fix this issue in kooka, xsane and xscanimage. The option is marked as experimental

Should I file a bug on linux-source package?

[Ben Collins (ben-collins)]

Unfortunately this option needs to remain enabled so that a good chunk of other users can have suspend/resume, which ultimately is more important than a working scanner.

Hopefully someone sooner or later will fix this properly.

[André Barmasse (barmassus)]

Bug is confirmed in Ubuntu Feisty with a Canon N1240U Scanner. The scanner is recognized when plugged in ("dmesg" and "lsusb" list it correctly), but scanning with any GUI (xsane, gnomescan or from within GIMP) is not possible. Using "scanimage" from the command line works, but even that sometimes needs a kick off by first invoking "sane-find-scanner" and then "scanimage -L". After that, the scanning starts smoothely.

Until the kernel/sane problems are solved I propose a small workaround. Edit the file .bashrc in your home directory and add the following alias (everything on one line, modifications of are up to you):

alias scan='scanimage --format tiff --resolution 300 -x 215 -y 297 > ~/Desktop/scanned_image'

From now on you can scan an image by simply typing "scan" in the command line. The file will be saved as TIFF with a resolution of 300 dpi as scanned_image to your Desktop. And dont' forget: If it doesn't scan, you have to try "sane-find-scanner" and/or "scanimage -L" first. Good luck!

[llimaa (llimaa)]

I have the same problem with my Canon Lide 20!

Here the Scanner works with the original Feisty Herd5 Iso release(kernel 2.6.20-9 without any updates) but stopped working after applying all updates incl. kernel 2.6.20-12. A reboot with the kernel 2.6.20-9 after applying the updates, don't solved the problem.

So i think that the problem is not only caused by that (USB selective suspend/resume) kernel option!

[Ian (superian)]

And another confirmation. Canon LiDE 20, recognised (although not quickly) but that's about it.

Ben said "which ultimately is more important than a working scanner". Well, it depends who has the scanner :) and I'd be surprised if this is the only USB peripheral that's been broken.

My current workaround is to reboot to an earlier live CD and save to a memory stick, but I'll give the other suggestions a go.

[renbag (renbag)]

I noticed the same problem with a HP ScanJet 4070 (hp3900 backend) and with an Epson Perfection 1260 (plustek backend). The scanners were perfectly workig in edgy with xsane.

[Ulisse (ulipo)]

Canon LiDE25 on Feisty, same as above.
Scanning thru command line works.

[Jorge Castelao (jcastelao)]

The same problem with a Canon LiDE30 (Bus 002 Device 008: ID 04a9:220e Canon, Inc. CanoScan N1240U/LiDE 30). It works properly under Dapper and Windows, but not under Feisty fully actualized.

[Christian González (droetker)]

confirmed for Feisty with all updates (29.3.07) or from Live-CD:
Canon N650U doesn't work.
Same machine with edgy works out of the box.
Is anyone working on this?
I need a working scanner more than suspend/resume...

[Clay Weber (claydoh)]

As I was informed, the USB_SUSPEND seems to be needed for many people to be able to suspen/resume their laptops, and there are a *lot* of laptops out there these days. I think it has to be fixed in the sane code, not in the kernel, but there are not enough entries in Sane's bug reports/mailing lists

Maybe adding to the existing bug report there might get some attention?

[llimaa (llimaa)]

@Clay Weber: In Debian Etch it works fine and iirc it's even the same xsane version as in ubuntu feisty. So the problem cant be the xsane code! But maybe depends of compilation options or something else.

[Dean Loros (autocrosser)]

I am wondering how this is to be resolved then. Scanimage works, but Xsane won't. What information do you need to help find the error?

[Clay Weber (claydoh)]

@ llimaa, as I noted, if you compile a kernel without USB_SUSPEND, it works fine. and as Ubuntu kernel dev Ben Collins also noted, this option is needed for laptop suspend/resume, so either libusb or sane-backends/xsane/kooka/quiteinsane/etc needs to be patched somehow to resolve this. And as i don't see *all* scanners broken, I am guessing this may need to be done for each sane backend (driver) that is exhibiting these issues. Easier than kernel/libusb hacking I am sure.

I have lost the link, but I did find that someone had determined that the scanners were being set to 'sleep' much too quickly so the scanner never even starts, or for those that do, it stops before finishing its path

now to see if i can find where I discovered that information.......

[Clay Weber (claydoh)]

@ Dean Loros;
I really have no idea, no one with the technical knowledge has afaik responded to any of the bugs in sane's bug tracker, and only one response in their mailing list.

[Dean Loros (autocrosser)]

So this seems to be a problem with interaction of some of the sane backends & hal/udev/USB_SUSPEND. Looks like some of the backends need to access USB "differently".

[Dean Loros (autocrosser)]

I just got some information from sane-development-list

Subject: Re: [sane-devel] LIde 20 scanner & kernels newer than
 2.6.20-9 (snip)

I'm using backend with no problems in kernel 2.6.20 disabling such
option. Most backends use libusb to establish communitation between device
and PC. Libusb doesn't provide functions to check that condition. May be
I'm wrong but If it's not a kernel problem (USB_SUSPEND is yet experimental)
I think that problem must be fixed in libusb libraries.

Jonathan Bravo

I an going to file this with libusb & point to this bug.

[renbag (renbag)]

I have recompiled the ubuntu feisty kernel disabling the 'USB selective suspend/resume and wakeup' option, but in my case the problem remained. With my HP ScanJet 4070 (hp3900 backend) xsane freezes while triyng to find the device. xscanimage, instead, works if the correct device name is supplied.
I then used strace to see what happens with xsane and found that it was continuosly writing to /dev/parport0:

...
open("./geniusvp2.conf", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/etc/sane.d/geniusvp2.conf", O_RDONLY) = 6
fstat64(6, {st_mode=S_IFREG|0644, st_size=877, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7329000
read(6, "# geniusvp2 backend configuratio"..., 4096) = 877
read(6, "", 4096) = 0
close(6) = 0
munmap(0xb7329000, 4096) = 0
open("/dev/parport0", O_RDWR) = 6
ioctl(6, PPCLAIM, 0x825a1c8) = 0
ioctl(6, PPGETMODES, 0xbf98baac) = 0
ioctl(6, PPWCONTROL, 0xbf98ba80) = 0
ioctl(6, PPWDATA, 0xbf98ba80) = 0
...
ioctl(6, PPWDATA, 0xbf98ba80) = 0
ioctl(6, PPSETMODE, 0xbf98ba80) = 0
write(6, "\0", 1) = 0
write(6, "\0", 1) = 0
...
write(6, "\0", 1) = 0
write(6, "\0", 1) = 0
write(6, "\0", 1 <unfinished ...>

Finally I found that removing the 'ppdev' kernel module (rmmod ppdev) solved the problem.
This module was not automatically loaded in edgy, but I have read that it has been introduced in feisty to allow automatic detection of parallel printers.
I tried this also for an Epson Perfection 1260 (plustek backend) and it works too.
So maybe that the problem is not the 'USB selective suspend/resume and wakeup' option but the 'ppdev' kernel module.

[Clay Weber (claydoh)]

disabling ppdev didn't help in my case. On my canon LiDE25 9plustek, it does let e get a preview scan (as it would on occasion let me) but the scan head does not return all the way (also as would do when it would actually scan) and on a second scan attempt, it would do the ususal.

What specific command can I run, and where do I look do get strace results for comparison?

[Dean Loros (autocrosser)]

I also tried disabling ppdev with no positive result. It seems like there are several problems with the backends, depending on which one you need/use.

Renzo--I would think that you should open a seperate bug for your problem, and link it to this bug. I am hoping that with enough problems, we will get some "love".

[renbag (renbag)]

I used this command to get a strace dump: 'strace xsane 2&> dump.txt'
If it hangs you have to kill the process, otherways it will continue to write to the dump file.

I have also replied to another bug which was already reported for an Epson Perfection scanner:
https://bugs.launchpad.net/ubuntu/+source/sane-backends-extras/+bug/88672/

[lnxzilla (todorz)]

Same issue with my LiDE 30, however downgrading sane-backends didn't fix it. Fixed after removing `USB selective suspend/resume and wakeup' as suggested by Achim Strobelt above. My kernel is 2.6.20.4, libusb 0.1.12.

[ianrose (ian-themagictree)]

Bug still here on a LiDE20 - hopefully this will be fixed (or a workaround found) by release. Feisty supported ALL my hardware nicely up until the last few weeks, unlike Dapper and Edgy, so it's a bit heartbreaking to see another bit of my hardware support dropping away :(

[howtoforums.net (jbaloul)]

Same problem here...this is a very painful showstopper...we have multiple Cannon LiDE scanners in our organization and we cannot upgrade due to this issue.

Please help fix this before release,

Thanks,

[Thomas (thomas-pabst)]

Hi,

I have the same thing here, with my canoscan lide 25.
Bus 002 Device 011: ID 04a9:2220 Canon, Inc.
is it this bug fix before release

[kervel (frank-dekervel)]

same problem here, with LIDE 30, and indeed scanimage cmdline works fine. i understand it is a kernel/libusb issue, but i wonder why the commandline version manages to scan.

[Arthus42 (arthus42)]

I have the same problem and switch backed to Edgy Eft. I´ll hope they fixe the problem, otherwise i don´t want to change to feisty wich seems to be good.

[ianrose (ian-themagictree)]

The kernel has gone from 2.6.20-14 to 2.6.20-15, but this regression is still unfixed - like a large number of people I bought this hardware specifically due to its mature support under linux. I don't really understand why experimental suspend/resume functionality for laptops should be allowed to break support for scanners attached to desktop machines - is it not possible for the installer to detect laptop/desktop initially, and install laptop-specific stuff like this (and NetworkManager!) only for laptops?

[ianrose (ian-themagictree)]

Workaround to enable GUI tools:
I can use the command line workaround mentioned earlier, but it isn't acceptable for the rest of my family. I have written a short shell script that "prods" the scanner every second and stops after around 15-20 minutes. This enables the standard GUI scanner utitlities (Kooka and so on) to work. Apologies for the quality of the solution, as I am far from a skilled technical type, however I don't think anyone is likely to sort this problem out so close to release.

1. Find the device using "lsusb":
for me:
Bus 001 Device 004: ID 04a9:220d Canon, Inc. CanoScan N670U/N676U/LiDE 20

so my scanner is on bus 001, device 004 - these numbers are used in the "wake-up" script as follows:

#!/bin/sh
echo "prodding scanner begins ..."
         for i in `seq 1 1000`;
        do
cat /dev/bus/usb/001/004 > /dev/null
sleep 1
        done
echo "scanner is now having a nice rest..."

save the above as "scantouch.sh". Activate the script by typing "sh scantouch.sh" - while the script is running (around 17 minutes max), the GUI scanner utilities can be used. Thanks to this horrible hack, my wife is able to get on with her work, and my ears no longer ring!

Warning: This worked for me, it might not for you, it might not be safe, there are surely better ways of doing this.

[Slava-f (slava-f)]

I also have some problems with Mustek BearPaw 1200 when using sane-backends-1.0.18. The obtained image looks overexposed - I suspect that there are problems with calibration. Downgrading to sane-backends-1.0.17 solves this problem.

[Václav Slavík (vslavik)]

This helps:
http://www.nabble.com/USB-Problems-with-Ubuntu---workaround-t4260039.html

[Hurikhan77+bgo (hurikhan77+bgo)]

Same problem here with this hardware:

jupiter linux # lsusb
Bus 002 Device 017: ID 04a9:220d Canon, Inc. CanoScan N670U/N676U/LiDE 20

If you keep the device awake with

while true; do sleep 1; cat /dev/bus/usb/002/017; done > /dev/null
(replace 002 and 017 with your bus and device id from lsusb)

you can do a preview and a full scan in e.g. kooka, but usually only one time. When it stops working, the scanning application has to be restarted. Looks like the backend or libusb cannot keep the device awake long enough.

Ideas for this found here: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/85488

[Sitsofe Wheeler (sitsofe)]

It looks like regularly blacklisting USB devices in the kernel will soon be at an end. According to this git commit http://git.kernel.org/?p=linux/kernel/git/gregkh/usb-2.6.git;a=commit;h=7d2c592609a7da950b458403f1936d382f38ff9c USB autosuspend will be disabled for everything bar USB hubs. I suspect those devices (or perhaps categories of devices) that do suspend can probably be dealt with by HAL and perhaps put into some sort of whitelist. Some of the discussion leading up to the change can be read on http://kerneltrap.org/Linux/Whitelists_and_Blacklists (which mentions that nearly 2/3rds of all printers can't cope with USB autosuspend).

Will this change be backported to Ubuntu Gutsy?

This bug would also benefit from resolving bug #3382.

[huffylinux (huffylinux)]

After upgrading to 7.10 Gutsy, I no longer need to run the kernel that had no suspend compiled in it. My scanner is working fine.

After the initial post-upgrade restart, it did take awhile for the 1st preview to run after xsane was started. If xsane was left running, subsequent previews were as fast as usual.

Now that I shutdown and restarted, the scanner works as expected.

Since upgrading to Ubuntu 7.10 (kernel 2.6.22-14-generic) my Canon N1240U works perfectly. No suspend issues, no scanning black pages.

[Leann Ogasawara (leannogasawara)]

This bug was marked "Fix Released" against the 2.6.22 Gutsy kernel. Just adding a note that the 2.6.20 Feisty kernel task is being closed as this does not qualify for a stable release update - https://wiki.ubuntu.com/StableReleaseUpdates . If anyone is still experiencing issues, please test against the latest Hardy Heron 8.04 Beta release and open a new bug report if the issue still exists: http://www.ubuntu.com/testing. Unfortunately, sifting through 450+ comments and 17 duplicate bug reports it not exactly easy on the development teams trying to resolve any remaining outstanding issues. Thanks.

Unfortunately Hewlett-Packard ScanJet 7400c also is affected by this bug.
I tried sane-backends-1.0.19 and my scanner was not working at all. I recompiled kernel without USB suspend support and still no go.
Downgraded to 1.0.17 and everything started to work.
With 1.0.18-r6 it's starts to scan but hangs in middle of A4 sheet.

~x86 2.6.24-gentoo-r4

sane-backends 1.0.19 had some problems that while probing backends the epson2 backend did not properly release the device. This is fixed in 1.0.19-r2 - could you perhaps try this version?

[Frederic-heulin (frederic-heulin)]

I don't when the variable was first introduced but for canon lide25,
SANE_BACKENDS should be setted to plustek and not canon in make.conf
sane-find-scanner look for the sane db so no problem but scanimage -L needs the correct backend to be available to test the device.
This solved the problem for me.

I have the same problem on my Hardy (2.6.27-7-generic). My scanner (UMAX, forgot the type) at home works perfectly without any hassles of scanning any document.

But I'm now outside my hometown and I have to scan some pictures for my homework. Here, there is an EPSON Perfection 660. Because no drivers released for Windows Vista for this model, I have been trying to use my hardy.

I just plugged it into one of my USB socket in my laptop. At first, it was unable to access the scanner at all so I installed the firmware file to "/usr/share/sane/snapscan" and input the firmware file location to the config file in "/etc/sane.d/snapscan.conf".

Then I opened Xsane. It worked fine in a few seconds when I tried to scan a book cover in Xsane, and in several seconds, Xsane was no longer able to access my scanner. I restarted Xsane but now It didn't even able to contact my scanner. Then I restarted my computer for several times and it didn't work at all.

So, I googled around and tried to install scanbuttond: No luck. Using other programs didn't give me any outcome to be able to access my scanner. I have also tried to use the command-line method "scanimage" and it produces the same error as in Xsane.

Please help me as I have to finish my work during next two weeks.

This should work for permanent settings:

sudo echo "options usbcore autosuspend=-1" > /etc/modprobe.d/usb_suspend
after this us should reboot.

this is for temporary:

sudo su
echo "-1" > /sys/module/usbcore/parameters/autosuspend

after this you need replug you scanner.

-1 mean - disable autosuspend
2 mean - enable autosuspend with delay 2 seconds

Please close--has not been a problem for quite a while...

[Jeremy Vies (jeremy.vies)]

I guess so.
