This problem is occuring with any multi function usb device that supports [scanning and [printing or cardreader] ].

The problem is that the usblp and/or usb_storage kernel modules claim the usb device (at least de sub-intrefaces for printing/usb storage).

The sane usb backends seem to try to claim the whole usb device, but this is rejected as the "other" interfaces are already claimed.
There seems to be a workaround in sane 1.0.17-1 that ignored the EBUSY state of the usb device, which worked for most devices.
Somehow this seems to be broken in the newer versions.

One solution to use the scanner is to do "modprobe -r usblp" and "modprobe -r usb_storage" before scanning and re-insert the modules using "modprobe usblp; modprobe usb_storage" afterwards but this seems no practical way to work...

You may try to downgrade the sane packages to 1.0.17-1 (some websites show that 1.0.18 also works) and try with these.

I have the same issue with a Debian system and a Brother MFC-215C, having scanner, card reader, printer and fax function.

I will try this downgrade fix next week and report back.

[Jeff Fortin Tam (kiddo)]

Ew, I tried the modprobe trick, and even after re-modprobing (and usblp and usb_storage are indeed listed in lsmod currently), now I can't use the scanner: it gives an error about invalid argument or something.

[Jeff Fortin Tam (kiddo)]

Well, I was ready to panic, but then I just removed the settings in ~/.sane/xsane and now it works without any problems. No i/o or arguments error.

That sneaky bastard.

[Guillaume Millet (guimillet)]

The version 1.0.17-1 does not contain libsane-pixma. I have the same problem with a Canon MP360. I did not succeed to scan with modprobe trick. I still have "usbfs: process 3022 (scanimage) did not claim interface 0 before use" messages.
The only way I succeeded with is to use the version from http://home.arcor.de/wittawat/pixma/

[Guillaume Millet (guimillet)]

And the problem continues with the 1.0.20-4ubuntu2 version in Karmic.

[Michiel Eghuizen (michieleghuizen)]

Same problem here with a Brother DCP-7010 USB scanner. Although, I'm using the latest Debian unstable version and not Ubuntu. But because I know Ubuntu is using Debian packages, I would say it here as well.

Version: 1.0.20-6

[Michiel Eghuizen (michieleghuizen)]

I still have the same problem in Karmic.

I have found a kind of solution, but I'm not sure if it even solves the problem:

I added the module 'usblp' to the file /etc/modprobe.d/blacklist.conf
  blacklist usblp

And added the device to the following udev rules file /lib/udev/rules.d/40-libsane.rules
  # Brother scanners
  ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes"
  # Brother DCP-7010
  ATTRS{idVendor}=="04f9", ATTRS{idProduct}=="0182", ENV{libsane_matched}="yes"

[Flo (doc-nice)]

It does solve the scanning of course, but without usblp, you will not be able to print any more, do you?

Jean-François Fortin Tam mentioned removing the sane-user-config, maybe that helps you, too?
BTW. Jean-François, you'd have had to scan without usblp inserted, not after re-modprobing it, I think that was the problem in your first post...

I cannot test any more as I no longer work in that company having this problem... :D

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Rolf Leggewie (r0lf)]

Is this still an issue in precise or later?

I can reproduce it on 12.04 with canon Lide 110

I have same issue in 12.04 with Canon MF5750

[David Newman (drdrnewman)]

The problem has reappeared in the latest three Ubuntu kernels, including 3.16.0-31-generic. I can no longer scan.

There seems to have been a change that meant the system started to recognise the card reader in my Canon MP550 printer, so I get messages like:

[ 386.757298] usb 2-1.5: SerialNumber: 14E912

[ 418.123578] usb 2-1.5: usbfs: interface 2 claimed by usb-storage while 'skanlite' sets config #1

I blacklisted usblp, as CUPS no longer needs it, so I can print. But when I tried to blacklist usb-storage, it was ignored.

In any case, I do use other usb-storage devices.

Is there a way to tell Ubuntu to ignore the card slot inside the printer, so not use usb-storage?
