Brother DCP7030 scanner: Invalid argument


Hello,

I am using 64-bit Debian Sid with 3.2.0-4-amd64 kernel. I had no problems installing Brother DCP7030 printer with official drivers from Brother's page, but I can't find any way to get scanner working. I've installed sane and libsane-1.0.22-7.4, brscan3-0.2.11-5.amd64 and brscan-skey-0.2.4-0.amd64 packages, copied the lib64 libraries mentioned in the Brother's FAQ.

I've modified /lib/udev/rules.d/60-libsane.rules adding
Code:
# Brother DCP-7030
ATTRS{idVendor}=="04f9", ATTRS{idProduct}=="01ea", MODE="666", GROUP="scanner",  ENV{libsane_matched}="yes"

# The following rule will disable USB autosuspend for the device
ENV{libsane_matched}=="yes", RUN+="/bin/sh -c 'if test -e /sys/$env{DEVPATH}/power/control; then echo on > /sys/$env{DEVPATH}/power/control; elif test -e /sys/$env{DEVPATH}/power/level; then echo on > /sys/$env{DEVPATH}/power/level; fi'"

LABEL="libsane_usb_rules_end"
User pawel is in groups ld and scanner.
At the very end of /etc/sane.d/dll.conf, there's "brother3" line.

Now when I plug in my printer I can see dmesg:
Code:
[ 8695.435420] usb 2-2: new full-speed USB device number 4 using xhci_hcd
[ 8695.470593] usb 2-2: New USB device found, idVendor=04f9, idProduct=01ea

But after all, after every first plugging in, scanimage -T gives me:

The same happens with xsane and simple-scan, and when giving commands from root account. Switching to kernel 2.6.32-5-amd64 doesn't help, either.

I know there are a few similar problems out there on the forums, but for me simply changing the access rights and groups does not work. As far as I know, gnome-keyring warning is irrevelant.

Hi:

Are you sure the keyring is irrelevant?
http://crunchbang.org/forums/viewtopic.php?id=19541

http://hongouru.blogspot.com/2012/07...g-couldnt.html

Maybe a cups driver will help.
http://packages.debian.org/sid/printer-driver-ptouch

Check in the booklet that came with your printer; more details on troubleshooting might be in there.

Hope this helps

It seems so - I've tried this on a Crunchbang liveCD without gnome-keyring problem, and it was the same.
I repaired it on my present one using your suggestions, and still, nothing changed.

Printer driver didn't work, either, and I have no idea what should I look for in a Brother booklet. I remember scanner working flawlessly under Arch and Ubuntu some months ago, so it is possible, and I suspect some newer version of... sane? kernel? broke the compatibility.

I gave thought to moving forward to a newer version of the kernel; generally does the job.
Even sometimes rolling back to an older version of the kernel too- But I know; you already did that-

Hmm...Not sure what this compatibility issue is.

Since your printer did perform under Arch and Ubuntu I suspect that this compatibility is of some sort of configuration. I'm wondering if re-configuring the 'printing' config file would make any difference.
However; I'm not sure how to change that file for the printer to comply.

I'll continue a little re-search and see if I find anything else you could try.

As crazy as it sounds; (this may be the answer) what is it that Arch and Ubuntu have (if anything) that Crunchbang lacks?

Is your Brother printer wireless?


Here is the manual for your printer. Maybe there is something in the manual for 'Troubleshooting' that might be helpful-

Found Brother Help Pages:
http://welcome.solutions.brother.com...n/faq_prn.html

If you haven't tried this cmd already give it a go-
Code:
sudo /etc/init.d/cups restart

They have some other libraries, and different defaults in the configs. I've tried, hovewer, running Ubuntu 12.04.1 LiveCD and installing my Brother - and what's interesting, it didn't work. The last time it did was on installed Ubuntu 12.10 though, and I'm gonna try it again.

My printer isn't wireless, I connect it to my laptop via USB.

Also, restarting cups didn't help.

My best guess is that some sane libraries can work only with the newest kernels. I'll try upgrading to absolutely bleeding edge one.

Sadly, linux-image-3.7-trunk-amd64 doesn't change anything.

The latest stable kernel (3.7.1) didn't help either?
http://www.kernel.org/

This is rare.

Sitting back and thinking more on this at the moment-

As you know Sane defines the programming interface (API) that's used to communicate between frontends and backends.

Wonder if there is something incorrect in the sane-utilities file?
/usr/share/doc/sane-backends-1.0.9/sane.ps?

http://linux.about.com/gi/dynamic/of...er-geinitz.de/


The new Sane backend tar.balls have been divided into multiple parts. Directions are in the "Read Me" file
http://linux.about.com/gi/dynamic/of...tang.com/sane/.

Hope this helps; I'm running out of ideas.
If needed I'll ask a Moderator to help-

Found this at crunchbang.org
http://crunchbang.org/forums/viewtopic.php?id=15104

[SOLVED]

Problem solved:

Installed a few gutenprint utils - it seems that these are necessary for cups to communicate with some printers, but are not included in the printing-support script.

I think this might be your answer.
Might be a permission problem like this man (Luctor) in a Fedora forum said-

Ztcoracat, thanks for all your help, but sadly, none of this works.

Kernel 3.7.1 only breaks the graphic and wifi drivers (installed it from package without non-free modules).

I don't have sane-backends package in my Debian, only sane-utils. Should I compile SANE manually?

Gutenprint brought nothing new. I lacked cups-driver-gutenprint, but it didn't change how sane behaves.

As I said, priviliges are okay, as root can't scan, either.

And I tried rmmoding usblp. Nothing changes.

I'm sorry DuskGlow:

I have told you everything that I know to try.

Would you like me to get another Senior Member or Moderator involved?

Done
In this new thread in 'General' you'll find where I have requested for a Moderator or Senior Member to come and help you in this thread.
http://www.linuxquestions.org/questi...ng-4175445322/

Hang in there. I believe that others will find or know what it is that we may have overlooked or just don't know ourselves what else to try.
