xsane not aquiring images from Lide 30

[mistr]

Ubuntu 17.10, xsane 0.999

During the "searching for devices" phase I can hear the "usual" tick from the scanner.

When I try to scan the error "Failed to start scanner: Error during device I/O" occurs.

I can dual-boot my machine into Ubuntu 14.04 LTS with xsane 0.998.
There it works perfectly (same computer, same port, same cable).

I don't see any messages on the console or in /var/log/messages.

I've tried running it as root - same problem.

Any hints?

Thanks

Mike

I got xsane running by copying the content of /usr/lib/x86_64-linux-gnu/sane from the old Ubuntu 14.04 (64 bit) installation to the same location in my Ubuntu 17.10 (64 bit) install.

According to

  sane-config --version

the "old" libraries are from the release 1.0.23. (And the naming of the files also suggests that.)

I then tried to compile sane from source according to https://help.ubuntu.com/community/CompileSaneFromSource in the hope to bisect the commit where this change happend:

sudo apt-get install libusb-dev build-essential libsane-dev
sudo apt-get install libavahi-client-dev libavahi-glib-dev

git clone git://git.debian.org/sane/sane-backends.git

./configure --prefix=/usr --libdir=/usr/lib/x86_64-linux-gnu --sysconfdir=/etc --localstatedir=/var --enable-avahi
make
sudo make install

After each install I rebooted the machine in order to flush any cached libraries from memory.

This first attempt did not work. (Same error as described above).

I then tried the various newer releases and one older one (1.0.22):

git checkout RELEASE_1_0_xx

configure, make, make install, reboot, test.

However, all of those fail.

The only version that works every time is the one I've copied from Ubuntu 14.04.

At this point I don't know how to proceed.

Status changed to 'Confirmed' because the bug affects multiple users.

Seems to be a problem with 18.04 too.

Issue about to be fixed in 18.04.
