scanner not detected
I have Ubu 14.04 on one partition and I just updated from Ubu 15.10 to Ubu 16.04 on another partition. In 14.04, xsane works fine. In 15.10, I could not get xsane to find the scanner. Now I upgraded to 16.04 and xsane still finds no device.
The scanner works fine in 14.04. Never worked in 15.10, won't work now in 16.04. The scanner is part of an all in one scanner printer Epson L351. It works fine in 14.04. I borrowed a simple canon flatbed usb powered scanner. Xsane finds it and it works in 16.04. I did not have to set anything at all. Just works, as does my Epson in 14.04. This is the output of sane-find-scanner and scanimage -L Quote:

I tried running xsane as root, got danger warnings, went ahead, but still no devices found. What is wrong here? I was hoping the upgrade would solve the problem, then I could move to 16.04 completely. |
Hi:
Got a few ideas- Reconfigure your kernel. Often times that will make things that didn't work work again. Maybe the wrong driver is loading first? If it is this will cause the device not to work. You might have to blacklist a driver. Maybe it's a backend issue? To find out if it's a permissions issue just run 'groups' in the terminal and see if you belong to the 'lp' and 'scanner'. If not add yourself to the group with the usermod cmd. Ubuntu 16.04 was just released (April, 2016) recently right? Maybe give the Developers time to get the bugs out. http://askubuntu.com/questions/36416...issions-issues http://forums.fedoraforum.org/showthread.php?t=304071 |
Eh, reconfigure my kernel? Sounds like something for experts, which is not my category, I'm more like 'dull witted beginner' category. Could I really do that??
Thing is, this was the same in 15.10, which has been out a long time. I hoped it would get better. The very same scanner works fine in 14.04 I made sure I am in the groups you mentioned: Quote:

Check that epson configuration file again. As far as I can remember, SANE requires either a usb vendor/model code or a scanner device created by a kernel module but not both. They interfere with each other. And the kernel scanner module is deprecated now. You're supposed to use libusb.

I went to the Epson webpage, downloaded and installed epkowa, which installs iscan, which is like their spin of xsane I suppose.
I noticed in /etc/sane.d/epkowa.conf that it said: Quote:
Long story short, now it works!! Problem may have been multiple .conf files in /etc/sane.de pointing at the same machine! No idea, but it works! Took me a year! Thanks for comments and tips anyway, very grateful! |
