Default list of scanner Sane backends all disabled #213

Closed xlwyx closed 2 years ago

xlwyx commented 3 years ago

It is not possible that the mentioned applications will not localize the scanner device. I used HP-scanjet-G2710 & Epson Scan-L475 (It's kind of outrageous.)...

You need to configure the drivers, all frontend applications will fail if the scanner isn't properly configured to work with SANE.

For the Epson, can't be preinstalled with GeckoLinux, download and follow the README instructions: https://download2.ebz.epson.net/imagescanv3/opensuse/latest1/rpm/x64/imagescan-bundle-opensuse-15.2-3.65.0.x64.rpm.tar.gz

The necessary SANE backend for the HP is already installed with GeckoLinux: http://www.sane-project.org/man/sane-hp3900.5.html

Hi, the problem seems to be here again. I tried to use Hp Scanjet 3880, that is working with, for instance, OpenSuse Leap 15.3, but the Sane does not find any scanner at all. The same with a pc where I have installed OpenSuse Tumbleweed. By the way my version of Gecko is rolling Plasma.

geckolinux commented 2 years ago

Hi @gioKheper , please make sure that the sane-backends package is still installed. It is pre-installed in GeckoLinux and includes the sane-hp3900 backend needed for your printer. http://www.sane-project.org/man/sane-hp3900.5.html

gioKheper commented 2 years ago

Hi, thank you. For what I can see the file hp3900.conf is there under /etc/sane.d directory and is configured as it should be. I tried to reinstall sane-backends, now at version 1.1.1-1.4, both on tumbleweed and on gecko, but with the same results, i.e. skanlite cannot find the scanner and ask to reload the list of scanners. I do not know if I am missing something else.

geckolinux commented 2 years ago

Could you also please check if sane-backends-autoconfig is installed?

gioKheper commented 2 years ago

Yes, it is installed both on Gecko and on Tumbleweed

geckolinux commented 2 years ago

OK, thanks for confirming that. Could you please post your /etc/sane.d/dll.conf from GeckoLinux and from a working vanilla openSUSE installation?

gioKheper commented 2 years ago

dll.conf.zip This is the one from the working OpenSuse 15.3

gioKheper commented 2 years ago

dll.conf.zip Thank you again. Hi this is the one from Gecko. I noticed that in this one the line hp3900 is commented, so I tried commenting it out and now it is working. I do not know why the dll.conf are different because I did not touch them, but now it is working. By the way my scanner is not connected via network, but just via an USB port.

geckolinux commented 2 years ago

Glad you figured it out. It looks like the dll.conf that openSUSE ships (and thus what GeckoLinux uses) has all the backends commented by default. I wonder if you used the YaST Scanner tool under Leap 15.3 to automatically enable the hp3900 backend. But thanks for bringing this up, it looks like things could be optimized a bit for out-of-the-box scanner functionality in GeckoLinux.

gioKheper commented 2 years ago

Well, I am not sure I used Yast.scanner for openSuse 15.3. I tried to use it with Tumbleweed and I got 2 strange things:

  1. I plugged in the Hp3800, started yast.scanner: the program showed the scanner but not configured so I was not able to test it.The file dll.conf was untouched. After I commented out the proper line hp3900, the program showed me the scanner as configured and I was able to test it.
  2. I plugged in another scanner I have, an HP5300C recognized as avision. This was properly recognized as avision and configured, and the dll.conf was changed. By the way I was not able make it running because I got an I/O error (This is an error I get for this scanner on any linux I use now, so not sure the problem is a now broken scanner that was working fine with very old linuxes many years ago or a problem with the avision backend, I need to investigate,but not now)

Hopefully improved in the latest GeckoLinux release.
