sane-find-scanner does not detect Brother DS-720D but simple scan and xsane does

I have Brother DS-720D and connected it on a newly installed ubuntu 16.04. I installed the drivers libsane-dsseriesfrom Brother's website. The scanner works and xsane and simple scan detects it. However using sudo sane-find-scanner does not detect it and simply outputs the #No USB scanners found. I verified that the libsane-dsseries.so files are in the /usr/lib/x86_64/sane folder. I tried other solutions like:

1. Reinstalling the drivers
2. Verifying that from lsusb it is detected

3. Editing the /etc/udev/rules.d/60-libsane.rules and adding the lines:

   #Brother
   ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes"

Sorted by: Reset to default
