scanner not working after upgrade to Dapper

[ainsaur]

My Epson 3170 scanner was working fine before my upgrade to Dapper. It now won't work. I had reinstalled the iscan and iscan plugin files from epkowa. When I do sane-find-scanner, it finds it on libusb:003:002. However, scanimage doesn't see the scanner. Any ideas?

Had you recently powered up your scanner? I find mine shows up in sane-find-scanner a few minutes (!) before it'll actually work. (Of course, I use it infrequently enough that I forget, and get all confused about why it's not working...).

Another thing you could check is if /proc/bus/usb/003/002 is read/writable by your user. (sudo chown <your username> /proc/bus/usb/003/002 if not)

Strange...I did another sane-find-scanner and I got this...

found USB scanner (vendor=0x04b8, product=0x0116) at libusb:006:003

I didn't touch anything so why am I getting a different result?

[marble]

Well, the first number is the bus number. I'd expect this to stay constant if the device is plugged into the same USB port on your computer. The second number is the device number, which is likely to change as it's allocated sequentially, but can be reused (ie. the first device plugged in is 001, next is 002, but if you unplug that and plug another in, it might be 003 or 002, depending on whether the kernel decides to reuse the number or not. Also note that bumping the power cable to powered USB devices can be the same as unplugging it, so sometimes that can cause the device number to be reallocated...)

As far as I can see, there's no entry for your scanner in the default dapper udev rules, so you might want to add one so that it automatically gets the right permissions when it's detected.

I recommend adding a new file to /etc/udev (rather than editing an existing one; this way it won't get lost in an update):
sudo kate /etc/udev/99-epsonscanner.rules

Add these two lines (sorry, the second one probably wraps):
# Epson Corp.|Perfection 3170
SYSFS{idVendor}=="04b8", SYSFS{idProduct}=="0116", MODE="664", GROUP="scanner"

and save it. Now when you plug it in next it'll have the right permissions. You may still need to tell your scanning program to rescan to find it each time, but you'll save yourself the chmod step.

(You can file a bug against libsane to suggest they add those lines to the 45-libsane.rules file.)

[ainsaur]

I gave it a try but I'm still getting the "cannot send command to scanner" error and scanimage still reports that there are no scanners attached. Perhaps I don't have the right files installed. I don't know if I need all of these but this is what I have:

sane
libsane
sane-utils
iscan
iscan-plugin-gt

I've also edited the epkowa.conf file to include "usb 0x04b8 0x0116. Am I missing something here?

[ainsaur]

I have some other information. First, I did a clean install from the CD. I don't know if that information helps but I figure that the install reset a file that I previously had modified. Another bit of information is that when I try to start iscan from the console, I get this output:

alex@Kubuntu:~$ iscan
X Error: BadDevice, invalid or uninitialized input device 168
Major opcode: 145
Minor opcode: 3
Resource id: 0x0
Failed to open device
X Error: BadDevice, invalid or uninitialized input device 168
Major opcode: 145
Minor opcode: 3
Resource id: 0x0
Failed to open device

I hope that someone has other suggestions for me because this is getting pretty frustrating!

[marble]

Don't worry about those messages (See this post: http://kubuntuforums.net/forums/index.php?topic=5772.0 ).

What would be useful is the output of these commands:
dmesg
sane-find-scanner
ls -l /proc/bus/usb/003/002 (or wherever sane-find-scanner says your scanner is)
groups

[ainsaur]

Okay, here is the output for each command:

Seems you still don't have the right permissions on the file in /proc. You can do:
sudo chgrp scanner /proc/bus/usb/003/002
sudo chmod 664 /proc/bus/usb/003/002

but I thought that udev rules file mod should have done this automatically. (This way you'll need to issue those two commands after every reboot.)

[ainsaur]

I tried the commands and I got a strange result. After changing permissions, I tried "iscan" but I got the same result (cannot send command to scanner). I tried "sudo iscan" and nothing happened (not even the "cannot send..." error) for about 30 seconds. I closed the session and then "iscan" ran. However, my scanner didn't start up. When I clicked on the preview button, I then got the "cannot send command..." error message.

Here is the output from sane-find-scanner:

found USB scanner (vendor=0x04b8, product=0x0116) at libusb:003:002

Here is the output from ls -l /proc/bus/usb/003/002

[marble]

I'm afraid I can't help with iscan stuff, since I don't use that. (Personally, I use kooka from the kdegraphics, and that's on a non-ubuntu machine too for now.)

The permissions look right, since you can read/write that file since you're in the scanner group, so it's a mystery to me why iscan doesn't think it can send the command.

[ainsaur]

Do you know why I'm having trouble with "sudo iscan"? I expected to be asked for a password and then have the program start. Instead, it only seemed to start after I close the session. Also, are there other configuration files that I should I look at?

[marble]

That is strange. sudo sometimes doesn't ask for a password if you've recently successfully sudo'd something, but I can see no reason it would wait for the session to be closed. Maybe it's slow to start up? I expect it downloads firmware to the scanner on startup.

For me (note that I have an Epson Perfection 2480, and this is from a non-ubuntu system), I have edited /etc/sane.d/snapscan.conf to include the line:
firmware /etc/sane.d/esfw41.bin
and I put the downloaded esfw41.bin (firmware file) into /etc/sane.d

I can't find your Epson 3170 on sane-project.org, so I don't know if yours is snapscan based too.

[ainsaur]

I'm not sure what is going on either. Iscan generally loads up in a few seconds so I don't think that it is loading too slowly. Is there anything else I can check to make sure that I have the proper permissions?

[ainsaur]

I found out some more information. It seems that I don't have a scanner module installed. Here is the output from lsmod:

I then tried modprobe... and I got this:

alex@Kubuntu:/proc/bus/usb$ modprobe scanner vendor=0x04b8 product=0x0116
FATAL: Module scanner not found.

How can I find/install the scanner module?

[marble]

Apparently that module was removed in kernel 2.6.4, so now you must use libusb instead.

I've done some poking around, and found that there's also a /dev/bus/usb like /proc/bus/usb on ubuntu, so maybe you need to check permissions there too. Also, there's /etc/sane.d/epkowa.conf which should have a line like:
usb 0x04b8 0x0116

(Not usb /dev/usb/scanner0)

[ainsaur]

I'll look into it but I will be away for a few days so I'll report back on my success (or not) when I return. Thank you for your expertise and time in helping me to figure out what 's going on.

[metricus]

I will jump in this discussion since I have recently moved to Kubuntu from SUSE and I have a 3170 P Photo as well. I did not try to install it yet as I had other priorities but:

Someone said it is not supported by sane. Slightly wrong. the 3170 should work just fine.

I used suse 9.3 and kooka worked with the 3170 perfectly. There was however something wrong there too since with newer suse versions there were some issues with Kooka and 3170 but the scanner still worked fine with Iscan. I did not explore the issue so I can't give details.

I wanted to ask in this forum what could we do to have the Iscan package included in the repositories. There seems to be a source there on the epkowa.jp site so it should be feasible.
I will follow this discussion as I am interested in the setup method myself.

[alrac]

I'll wager this is a udev issue. *buntu kindly removed all the useful udev documentation, for which I have filed a bug report. First of all you want to find out if your system sees the scanner at all, then if you need to be root to use it:


$ lsusb
Bus 003 Device 003: ID 04B8:0819 Seiko Epson Corp.

Good so far. Now try:


$ scanimage -L
No scanners were identified. (etc blah blah)

Now as root:


$ sudo scanimage -L
password:
Device `epson:libusb:003:003' is a Epson Unknown Model flatbed scanner

So the USB subsystem recognizes the scanner just fine, but only root can make scans.

You can run Kooka as root and do scans just fine. However, to run as an ordinary user means you need to edit /etc/udev/rules.d/45-libsane.rules. The old chmod a+x /proc/bus/usb/003/003 trick doesn't work with udev.

When you examine the /etc/udev/rules.d/45-libsane.rules I think it's pretty clear how to add a line for your own scanner, using the information from lsusb.

I wish that *buntu had seen fit to not remove all the helpful udev docs, and that there was a scanner installation script that automatically detected scanners and wrote an entry in 45-libsane.rules.

This page is very helpful for understanding udev:

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
~$ sudo scanimage -L
Password:
device `epson:libusb:005:004' is a Epson* flatbed scanner
================
So far it works exactly as you said.

However, I made the modif in 45-libsane.rules:
# Epson Corp.|Perfection 3170 Photo
SYSFS{idVendor}=="04b8", SYSFS{idProduct}=="0116", MODE="664", GROUP="scanner

and even after reboot nothing changed. Scanimage -L brings the same message out.

I do agree that there should be an automated Scanner setup method in Kubuntu.

Modification:
Well, it's funny, after posting I noticed some missing " at the end of the string and I checked and found that I did miss the " in the added string in 45-rules. Did a reboot and now Kooka can access the scanner in user mode.
Thank you.

PS: there is still a small problem:
It still doesn't move the scanner. I assume however it is because the driver is not installed yet... :-[

I still have to see how to install epkowa.

[metricus]

OK, I installed iscan but this did not change a thing.

To mention here that I was getting the same error as ainsaur:
X Error: BadDevice, invalid or uninitialized input device 168
* Major opcode:* 145
* Minor opcode:* 3
* Resource id:* 0x0
Failed to open device
=====
then fixed it by commenting out the wacom entries in xorg.conf

Now the scanner still does not fire up:

~$ kooka
libkscan: WARNING: Trying to copy a not healthy option (no name nor desc)
libkscan: WARNING: Trying to copy a not healthy option (no name nor desc)
ScimInputContextPlugin()
~ScimInputContextPlugin()

and if I type iscan i get this:

Small note: my Kubuntu is not an update but fresh installed yesterday from dvd.

[alpa]

Also my experience is exactly like yours !
I have an Epson Stylus DX3800 (all-in-one) and it was working fine with Mandriva2006
Now I have Kubuntu Dapper and I can not scan. I have the same error !
Alpa

[metricus]

Yes, it appears to be an *ubuntu issue. Maybe someone with more experience could give us a push here...please.

So far the only valuable information which also made a difference was the one from alrac which has enabled any user to use the scanner and not only the root. However, I get the same messages whether I am root or user.

Changing permissions to proc/bus/usb/xxx/xxx (like was suggested earlier in the thread) does not help since at different boot times the system allocates different addresses to the scanner. now it's at 001/004. before was at 005/006.
Also changing the epkowa.conf file does not help. The usb entry is enough one does not need to force the backend to look at 04b8:0116

That's all I know so far

[metricus]

OK I cleared it up:

3170 is NOT supported by SANE therefore all attempts to make Kooka and other programs scan with this scanner will fail, AFAIK.

It can work however in Linux but only with ImageScan for Linux which a proprietary software from Epson.
So to get it going you may uninstall sane, xsane and even kooka and libkscan. And most importantly you MUST uninstall libsane-extras.

The only sane package you need is libsane.

Then download:
iscan-2.0.0-0.c2.i386.rpm and
iscan-plugin-gt-9400-1.0.0-1.c2.i386.rpm
from:
http://www.avasys.jp/english/linux_e/dl_scan.html
by completing the required fields
and then convert the rpm binaries to deb using Alien as instructed in the kubuntu wiki:
https://wiki.kubuntu.org/RPM/AlienHowto?highlight=%28alien%29
install the 2 deb files in any order and then start ImageScan with the command iscan

Please note that the modifications to /etc/udev/rules.d/45-libsane.rules, as suggested by alrac, are not needed in this case. AFAIK the reason this scanner is not on that 45-libsane.rules file, is because it is not supported by SANE.

My 3170 works now but only with Iscan. I am planning however to sell it on EBay cuz I had enough problems with it in Linux and purchase a Canon Lide or something that is well supported by SANE. I don't use the film scanning feature anyway..

I've done some poking around, and found that there's also a /dev/bus/usb like /proc/bus/usb on ubuntu, so maybe you need to check permissions there too. Also, there's /etc/sane.d/epkowa.conf which should have a line like:
usb 0x04b8 0x0116


I have already changed the epkowa.conf file and added a line but there is no change. As for the /dev/bus/usb, how do I check permissions?

[marble]

Type:
ls -l /dev/bus/usb/003/002 (or wherever the device is)
The first column should be something like crw-rw-r-- and the device should be in the 'scanner' group (4th column).

If the group is not scanner:

sudo chgrp scanner /dev/bus/usb/003/002

If the 5th-6th characters of the first column aren't 'rw':

sudo chmod 664 /dev/bus/usb/003/002

[ainsaur]

Here's the output:

crw-rw-r-- 1 root scanner 189, 641 2006-06-16 16:39 /dev/bus/usb/006/002

It looks like the permissions are set correctly but shouldn't the scanner be in my group (alex) instead of root? If so, how do I change the group to "alex"?

[marble]

No, that's fine. The second 'rw' means the group can read/write it. The device is owned by root, but it's in the scanner group (ls -l lists type in the first char (c=character device file), permissions in the next 9 chars, then the number of hard links to the file (not usually that useful), owner, group, size, last modified time, name).

So long as you are in the scanner group, you can read/write it. You can be in multiple groups at the same time. Type 'groups' to see which groups you're in. You should find yourself in the scanner group, amongst others.

(Your entry in /etc/passwd determines your default group - ie. the one files you create are in if you don't go anything to change that, /etc/group determines other groups you're in.)

[ainsaur]

Okay, if the permissions are fine, then does anyone have any other suggestions? I am totally stumped!

[ainsaur]

I've continued to try to run iscan and I have made some progress. When I select "New Root Shell", enter the password, and type "iscan", the program starts up. I don't hear the scanner "perk up", however. When I select "preview", I get the now familiar "cannot send command to scanner" box. Previously, I did "sudo iscan" and the program would not run. I don't know why there is a difference but there apparently is one. So, if iscan starts up, what still needs to happen in the background for the scanner to work?

[metricus]

This usually happens when you don't have the plugin installed. Check the posting I made above and install both files iscan and the plugin. I had the same situation and after i installed the plugin it worked.

[ainsaur]

I just tried uninstalling and reinstalling both files. This time, I got some progress:

alex@Kubuntu:~/Downloads$ scanimage -L
device `epson:libusb:006:002' is a Epson flatbed scanner
device `epkowa:libusb:006:002' is a Epson flatbed scanner

Having scanimage find the scanner is a minor victory. What I notice, however, is that it takes about a minute for scanimage to return the above output. I typed "iscan" and waited about a minute before the program started. Once again, there was no response from the scanner and when I clicked on "preview", I got the "could not send command to scanner". Is there some other way to check if the iscan-plugin is correctly installed or if it is running when iscan requests it?

The slowness of the computer is another issue. When I upgraded to Dapper, the computer was pretty fast (for a 1 GHz cpu with 256 Mb of RAM). After the first set of updates, the computer slowed down considerably. Has anyone noticed a generall slowing down of their computer? If so, is there anything I can do about it (other than starting a new thread on this forum)?

[metricus]

Are u sure that libsane-extras is not installed? the Epkowa driver in that package (also called free) conflicts with the one in the iscan plugin (also called non-free) and only the non-free one works with this particular scanner (Ep 3170).
My scanner works just fine with iscan. The command scanimage moves the scanner as well. The only things that don't work are kooka and the scanning plugin from Gwenview (they both use the same engine). I haven't tried xsane yet. Never used it...

I am discussing with someone from Avaya (makers of iscan) on the sane forum to try to determine why these frontends don't fire-up this scanner when apparently they should. I also had the same experience when I used SUSE 9.3 and after updating to 10.0 and then 10.1 experienced the same situation with kooka not working. There is something more to it than just drivers and settings since 2 distros are behaving the same.

As for you, I was thinking to suggest you reinstall kubuntu and the 2 iscan packages. The reason I suggest this is that I am sure that the scanner should work. It has worked for me in 2 distros exactly the same. Another reason is that in this thread there have been many suggestions made that are not needed and you should consider the possibility of making a modif and then having forgotten about it. Don't be mad at me if it still doesn't work but I guess it's not much to do and chances are high that you will get it to work.
Just make sure you don't install libsane-extras.

Try making a fresh install. Or maybe, if you can, create another partition and install another kubuntu there fresh and see if it works. This way you are not bothering other apps you may be using in your current installation.
I too have SUSE 9.3 in one partition and Kubuntu in another until I make sure that all features work to my satisfaction in Kubuntu and I can finally give-up SUSE.

Take care.

Thank you for your advice. I think that reinstalling is the best solution right now. I don't plan on doing it for another week or so because I've put a lot of time into getting this scanner to work to the detriment of other projects I need to take care of. Thanks, again, to everyone who has chimed in with suggestions. Good luck to those who are also still trying to get their scanner to work.

[metricus]

Alex if you still follow this thread I think I found the issue.
Also Just to recap a final conclusion on how to get this scanner working (Epson 3170 Photo)

download the Iscan package AND!! the plugin from here:
http://www.avasys.jp/english/linux_e/dl_scan.html
just go through the routine and dnload both files.

Then convert them with alien using the option scripts:

sudo alien --scripts iscan-2.1.0-1.c2.i386 (or whatever the current version is...)
NOTE: if you don't use --scripts it won't work!!

after this just install the packages. with this method only the package iscan and will work. If you want to have the package in the Kmenu you will have to edit the menu by hand and add a new entry called Iscan with the command iscan.
Xsane will also work after the Iscan-plugin install.
Note that only the package libsane is needed for Iscan and Xsane to work. Other packages like sane-utils are not needed unless you are using other programs.

The suggestion found earlier in the thread to add the scanner to
etc/udev/rules.d/45-libsane.rules is not needed for iscan to work. It is however needed to make
scanimage -L
recognize the scanner. Otherwise, only
sudo scanimage -L
finds the scanner.
Kooka will not work with this scanner no matter what. Kooka does not seem to be supported anymore as well as libkscan which appears to be the culprit in this matter. The 45-libsane.rules modification will help Kooka see the scanner but it will still not fire it up.

I hope this helps putting all suggestions in one post for future needs.
(I had done a reinstall myself and found out that it was not working again. My only mistake was that I had not used the --scripts option with alien. Luckily I remembered what I had done last time... 8)

I have however one last challenge/question. How do we make this work under AMD-64? The iscan plugin is binary only (non-free) and all we have is a i386 rpm.

[ainsaur]

I just tried to reinstall iscan and the plugins using --scripts. Unfortunately, iscan loads up but there is no "wake up" from the scanner. When I try a preview, I get the same old "could not send command to scanner". I'm afraid that I've tried so many solutions that I may have messed things up somewhere else. I think that I'm going to just wipe out the partition and do a clean install. I'm waiting for my Kubuntu disk from shipit to arrive before I try this (just in case there is something funny going on with my downloaded CD).

Maybe the reinstall will fix some other issues I've got, like my printer that now takes at least 2 minutes to print out anything that I send to it. Or, perhaps, the inability to print out files from Tuxpaint. Or maybe the overall sluggishness that I've experienced after installing my first set of updates. :)

Thank you metricus, and others, for all of your help.

[metricus]

May be worth a reinstall. I was getting the same exact message as you yesterday and I freaked-out...Only after I re-ran alien with scrips it worked. Last time I used scripts without paying attention. The only other time when I got this message was when the plugin was not installed.

I got a new mobo and AMD-64 3500+ and I have to say that I was surprised that in 64 mode it works just a little bit slower than 32 on the same machine (I have 2 versions of Kubuntu installed (64 and 32). It is strange however that the whole machine is now slightly slower than the old AMD 3000+ 32 bit that I had before. And I have a pretty expensive graphic card ASUS-N660 silencer which is slower than my old ATI radeon 9600. Very strange... 500$ later my machine is slower... Not a whole lot though but noticeable. I think the graphic card is to blame, I will investigate... I am digressing however...

So this is the reason I had everything wiped-out and made a clean install.
And Yes it is worth waiting for the original cd. I had only mishaps with the cd and the dvd downloaded through bittorrent.

The ftp download however worked well in all instances. Left it overnight and bam! (for the dvd)
Let me know when you reinstall. The procedure above is exactly what I did step by step.

take care.

First, I apologize if this post is a dup to an existing post under this topic. I just spent weeks trying to get my 3170 working under Dapper and I don't have time right now to go back and check all the previous posts for duplicates. I do however want to post a link to the fix I used successfully, since it was so useful and I think it simplifies the procedure, IMHO. I think the same procedure was mentioned earlier (here), but I think this link is worth posting since it's visually easy to follow. It worked first time for me, and my 3170 is finally working fine with Dapper. The link is below:
