Hi,

Recipes from Ubuntu bug tracker (not sure if it works:

https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1728012/comments/36

https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1707352/comments/116

In order to make a Brother MFC-5490CN work, I additionally had to do this

cd /usr/lib
sudo ln -s /usr/lib64/sane/libsane-brother3.so libsane.so
sudo ln -s /usr/lib64/sane/libsane-brother3.so.1 libsane.so.1
sudo ln -s /usr/lib64/sane/libsane-brother3.so.1.0.7 libsane.so.1.0.7

Scanning with MFC-5490CN now works with simple-scan.

Hope this helps.

Best regards,
Yuri
