The locations mentioned in the man-page are definitely correct for
Fedora and RHEL,  the only systems using systemd at the time I wrote
the systemd parts of the man-page (in 2013). For these distros they are
still correct.
Now Ubuntu may have changed some of the paths when it introduced
systemd. It may also be the case that Ubuntu does use an old version of
systemd that does not yet support the user specific units (in
/etc/systemd/user). Can somebody please confirm if other Ubuntu
versions (probably later versions) do use /etc/systemd/system?
If I can find some time I may try to clarify the man-page with the
alternate location if we can get more clarity on this.
BR, Louis

Re: [sane-devel] Epson WorkForce DS-1630

2017-11-09 Thread Isabelle Barbe 

Hi Olaf and Ralph !

Thank you very much for your prompt answer.

The last one was the XP-435, supported by their Image Scan V3, too, but 
XP-435 wasn't able to work properly with the SANE :( I had always to 
install the drivers before using it. It was so upsetting that we 
throught it away and bought a new Printer (Canon IP110) and now we are 
looking for a scanner which works with Linux (Image Scan V3 doesn't run 
properly in Linux and was enable to recognise this d.. scanner !!!).


As far as the WorkForce DS-1630 is concerned I've read that SANE doesn't 
run with USB3 ? and in the french description (easier to read when we 
are Frenches) I read that this one is just working with USB-3...


Have a nice day !

Isabelle

Thanks for the follow-up Ralph.

If the EPSON download site says it's supported by their Image Scan V3,
you should be able to use it with any SANE frontend after installing
Image Scan V3.

In addition, there is a *chance* that it works (to some extent) with one
of the epsonds, epson2 and epson backends.

Good afternoon !

Before buying this mentionned scanner I need to know if Libsane
recognise it. I don't see any mention about it at
http://www.sane-project.org/sane-mfgs.html#Z-EPSON.

That's because, unfortunately, EPSON does not provide information
linking model names to USB product IDs and SANE does not include third
party backend information in that page :-(

If EPSON provided the linking information, I'd be able to create a much
more useful utsushi.desc file.  And if SANE added third party backends
to those pages, you'd actually be able to find it.

# We could do something about the latter though.

You won't find the DS-1630 there (yet?), but, FWIW, the utsushi.desc
info is at

   http://www.sane-project.org/lists/sane-backends-external.html#S-UTSUSHI

If you can tell me the USB product ID for the DS-1630, I'll fix that
right away.

Hope this helps,

I'd gladly do so but ... seeing that you have trouble using it via USB
on your Mac, what makes you confidently say that this should be added to
the epson2.desc file?

Hope this helps,

Please take a look at the Directories section of the systemd manual page[1]
and the systemd.unit manual page[2] for Ubuntu 16.04LTS.

 [1]: 
http://manpages.ubuntu.com/manpages/xenial/en/man1/systemd.1.html#contenttoc5
 [2]: http://manpages.ubuntu.com/manpages/xenial/en/man5/systemd.unit.5.html

Based on my understanding of the documentation there, I would say that
Ubuntu's(?) saned manual page[3] (which is not modified from the one
that the SANE project ships in this respect) refers to the correct
directory locations.  If that in some way does not work, it's first and
foremost an issue with the Ubuntu tutorial[4] and Ubuntu's systemd
and/or SANE packages.

 [3]: http://manpages.ubuntu.com/manpages/xenial/en/man8/saned.8.html
 [4]: https://help.ubuntu.com/community/SaneDaemonTutorial

You may also want to take a look of the files provided by Ubuntu's
sane-utils package[5] and note that these files should be installed for
you by the package, completely obviating the need for you to configure
anything.

Hope this helps,
