XSANE looking for driver files in different paths

[Aveek Basu]

Hi,

Usually XSANE used to look for the driver files in /usr/lib/sane for 32 bit version of the Ubuntu OS and /usr/lib64/sane for the 64 bit version of the Ubuntu OS. This was the case at-least till Ubuntu 14.10. After that there seems to be discrepancies in the locations XSANE is trying to find the driver files. Details mentioned below:

OS locations searched by XSANE for the scanner driver files.

Ubuntu 14.10 (x86): /usr/lib/sane
Ubuntu 14.10 (x64): /usr/lib64/sane

Ubuntu 16.04\16.10 (x86): /usr/lib/sane
Ubuntu 16.04\16.10 (x64): /usr/lib/sane

Ubuntu 17.10\18.04 (x86): /usr/lib/i386-linux-gnu/sane
Ubuntu 17.10\18.04 (x86): /usr/lib/x86_64-linux-gnu/sane

So now the question is which should be the perfect path for XSANE to look for the driver files. If "/usr/lib/i386-linux-gnu/sane" and "/usr/lib/x86_64-linux-gnu/sane" are the confirmed new locations then the driver has to change. Need to know the correct path.
