Anthony Buckley, could you please advise to the results of 4.9-rc2? If
it is still reproducible in this, then this would be an upstream bug
also.

Title:
Network scanner not detected by xsane after upgrade to 16.04
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hopefully I'm reporting this in the correct area/group. Sorry if not.
After upgrading to 16.04, my scanner is no longer detected by xsane (and
other scan apps.) The model is 'Epson WF-3520' multi-function and is connected
wirelessly to the network.
The problem occurs on all my computers: A Dell 64 bit desktop, An Asus 64 bit
laptop, A Medion 32 bit laptop.
I've upgraded to the latest software released by the manufacturer on 2
computers, but it makes no difference.
Printing works OK and also the scanner is detected if I connect using a USB
cable (a second printer is installed though).
The problem only occurs using the 'linux-image-4.4.0...' series of kernels.
If I boot with any of the previous kernels available, 'linux-image-4.2.0...' or
'linux-image-3.19.0...' everything works OK.
I am able to ping the scanner.
I've tried a number of suggested fixes from searching around various forums,
although many of these relate to 'back-end' scanners connected to a host for
network access which is not applicable as mine is connected directly to the
network. In any case none have worked.
I have tried the following:
. Removing all manufacturer software and /usr/sane.d/epkowa.conf
. Comment out all entries in the /usr/sane.d/dll (Back-end related)
. Comment out all entries in the /usr/sane.d/dll.conf.conf except 'net' and
adding 'epkowa' (Back-end related)
. Disable the firewall (ufw)
. Specifically adding a port to use (1865) (ie. net 192.1... 1865
. Linking the libraries in /usr/lib/sane to /usr/lib/x86_64-linux-gnu/sane
Other than that I'm at a loss and sticking with older kernels.
Regards.
