I just plugged in my Epson Perfection 3170 Photo scanner. This is the second scanner that doesn't 'Just work' in Linux. Two in one week! :-O I just can't believe it.

It shows up in sane-find-scanner for root (not for my user) and does not show in scanimage -L or sudo scanimage -L

sudo sane-find-scanner

found USB scanner (vendor=0x04b8 [EPSON], product=0x0116 [EPSON Scanner]) at libusb:001:005

scanimage -L

No scanners were identified.

What gives? How can I get the scanner to show up in scanimage?

Like I said in my last thread, I have no idea how scanning works on Linux so any and all help is greatly appreciated.

what are the permissions? from root instance of sane-find-scanner # You may want to run this program as root to find all devices. # Once you found the scanner devices, be sure to adjust access # permissions as necessary.

just guessing, you/user does not have permissions to access libusb:001:005

It doesn't work as root either

sudo scanimage -L

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).

This is the one (see the vendor/product hex ID). *Unsupported* Comment says "supported by the epkowa backend plus non-free interpreter". Backend epson2 (1.0.124 (unmaintained)) Manpage sane-epson2 I think this means you need the proprietary driver package.

I think after you identified the scanner, you have to uncomment the proper driver module in /etc/sane.d/dll.conf.

YaST would do this automatically. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)

What is it you're doing to break these scanners? ;)

I have an Epson scanner which works well. However, it uses the Plustek drivers.

Believe me I would like to know as well. Usually everything on Linux works out of the box.

Saying that this scanner DOES work out of the box on openSUSE 12.3 but not on later openSUSE or Ubuntu 16.04, 17.10

I did have some similar issues with an Epson Perfection that did no longer work in Leap, related to what USB port/driver it is connected. Maybe read through the bugreport from that time, https://bugzilla.opensuse.org/show_bug.cgi?id=975866 and see if anything applies to your case, too? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Nothing has helped so far.

I just installed 12.3 in a VM and connected my scanner. It works! 13.1. Problem comes back.

Ubuntu 10 in a VM also finds my scanner and works out the box. Ubuntu 17.10 does not. Same problem.

I am trying to find out what the differences are between the odler OSes and the newer ones. I cannot see why they would remove compatibility? work

This is a very good quality negative scanner. I cannot find another model of the same quality (that isn't more expensive than buying windows) so it is imperative I find a solution (other than downgrading to an older linux).

Can anyone suggest some diagnostic steps? Any log files that could be useful?

I have no idea how scanners work in linux so I am currently stumped.

Have a look at differences in /etc/sane.d on both 12.3 and a non-working distro. Also in /usr/lib/sane . -- Gertjan Lettink, a.k.a.

This happens all the time. Drivers are removed for older hardware, for various reasons. Sometimes the driver has no maintainer. Sometimes it no longer compiles with current compilers. Sometimes it contains vendor binaries (e.g. firmware) that no longer work, say if they depend on old versions of libraries that the distro no longer includes. Sometimes the code of the driver contains assumptions -- such as that it's running on a 32-bit CPU -- that don't work on new architectures, so it no longer compiles and thus it gets remove. Sometimes the hardware is just plain bad in some way, such as the 3Com 3C501 ISA Ethernet card, which caused problems on any network it was attached to, so the driver got killed to stop people using this awful NIC. To give an example of a single-component update that removed a ton of device support, the switch from XFree86 to XOrg dropped a lot of drivers for old ISA and VL-bus graphics cards. But few people were using such old hardware. They just had to keep running older distros. The original Intel 80386 chip is no longer supported, even on 32-bit kernels. I think even the 80486 doesn't work any more: now you need one of the last half a dozen generations of 32-bit processors, and the first 2-3 generations don't work any more. This problem is as old as the x86 PC platform. Windows 3.0 could run on original 8088 and 8086 PCs, but it could not support VGA cards in them. The VGA driver used 80286 instructions that the 808x chip didn't have. If you installed an NEC V20 CPU, a socket-compatible replacement 8/16-bit CPU, then you could use VGA with Windows 3.0 on such a machine -- but now your vintage machine was no longer original. :-) It happens. It if works in a VM, use a VM! Install the guest additions and save your scans into the host's filesystem. -- Liam Proven - Technical Writer, SUSE Linux s.r.o.

I am trying to find out what the differences are between the odler OSes and the newer ones. I cannot see why they would remove compatibility? I told you that the "Perfection 3170 PHOTO" with vendor/model 0x04b8/0x0116 is simply not supported.

--> http://www.sane-project.org/sane-mfgs.html#Z-EPSON

Maybe it is supported by the proprietary driver package.

The page hints that it was supported by "epson2" (1.0.124) which is unmaintained.

If it works with older distros, then install one such old distro in a virtual machine.

Out of curiosity I disconnected my old Epson Perfection 1650 from an OpênSuse 13.2 machine to connect it to a Leap 42.3. The scanner was not regognised immediately ; but Yast proposed this driver : Epson GT-8200 at epson2-libusb:002.002 ; and it worked with Simple Scan. Yast lists 5 Epson Perfection 1650 drivers butit is specified that most of them are discontinued and are overseas versions of the GT-8200 which seems to still exist. I hope there is something similar for your Perfection 3170. -- Paul Ollion Linux OpenSuSE 13.2 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Is iscan installed in 12.3 and from what repo? zypper se -s iscan As Carlos already mentioned this probably needs proprietary driver. http://support.epson.net/linux/en/iscan_c.html There seems to be a build project for it that is up to date although not tumbleweed (no gcc49-c++) https://build.opensuse.org/package/show/home:awissu:NonFree/iscan Some pointers https://forums.opensuse.org/showthread.php/493559-Scanning-software https://ubuntuforums.org/showthread.php?t=1052521

[snip] Like I said in my last thread, I have no idea how scanning works on Linux so any and all help is greatly appreciated. Basically, the idea is to look at the list of supported scanners first, pick one from the list and THEN buy it. You'll be amazed how much luckier you get that way.

Searching the web for 'sane scanners' (no quotes) throws up lots of hits, but perhaps

http://www.sane-project.org/sane-backends.html

or

http://www.xsane.org/xsane-introduction.html

is a good place to start.

This scanner is supported. Or perhaps was. Works out the box on SUSE 12.3 clean install.

But does not work out the box on anything later. Or Ubuntu for that matter.

 - just been looking on Wikipedia : trying to get an idea what "Docker" is all-about :((

- could Scanner problems be solved by using Docker ??

If one installs a Docker unit , then loads into Docker

the last Linux Distro which is known to operate the Scanner properly , and then install Xsane for that distro onto the "Docker" ??

Can "Docker" be used to contain a Program that will never de-grade because current Libraries have changed ??

Is Docker the golden solution to preserving an old program so it can run 'forever' ??

......

Oh...? Interesting idea. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)
