[sane-devel] Canon Lide scanners stopped working in Ubuntu 16.04

[Dmitry B]

Hi everybody. Recently I used Canon Lide scanners 110 and 220. They used to
work in Ubuntu 14.04. In 16.04 they stopped working. I see an error message
"Device I/O error". There are many bug reports on Ubuntu's Launchpad, but
they look like abandoned:

https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1588878
https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1587853
https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1391038

The version of libsane is 1.0.25+git20150528-1ubuntu2 . I also tried to
build my own version from Debian experimental (1.0.26~git20151121-1), but
this didn't help.

The first link contains debugging information collected with scanimage
-L/-T and debugging environment variables. In there any chance to fix Caon
Lide scanners support?
