Hmmm...tried to copy and paste one file to /usr/lib but received a error message as per attached.

Just found this also:

Why can't i paste anything under the /usr/ folder?

You don't own this directory, since it is a system-directory and not a user-directory, like /home/, where you can copy/paste files as you wish!

Please don't change the root permission of any system-directory permanently, since your system manages on its own and you can only break it that way. Instead open up "Terminal" and use sudo before your command to copy cp, or move mv files/folders.

The -r stands for recursive, since it is a folder (parent), with sub-folders/files (children) and therefore mandatory!!

Points 3 and 5 under File execution seem relevant. https://community.linuxmint.com/tutorial/view/100

From a terminal:
Code:
sudo cp -r /usr/lib64/sane /usr/lib
or you could start a GUI filemanager using gksudo or gksu

I tried using GUI Krusader file mgm't app but it still would not allow me to copy the files. I'm not sure I want to copy those files as shown....found this in my reading:

"Unless you use Slackware or a similar distribution which has no package management system, you shouldn't write any files to /usr/lib and other system lib and bin directories. If you need to do that, do it under the /usr/local tree; in this case that would be /usr/local/lib. If you wish to write to that directory often, you may give yourself (or a group where you're in) write permissions (although that creates a bit of a security weakness). You should NOT do that to /usr/lib though!"

Hey Allen
Executed command "sudo cp -r /usr/lib64/sane /usr/lib" as suggested and it worked!!!! Scanner is now listed and works fine now. My whole intent with this exercise was to load Linux Mint 18 on my new Asus PC which now runs Windows 10. I wanted to make sure my hardware would work. In your opinion, were all the prior steps necessary or do you think all that was necessary was "sudo cp -r /usr/lib64/sane /usr/lib"?
I would never had figured this out on my own and I gained a tremendous amount of knowledge and a friend along the way.
Thank You so much for your help.
Dennis

Yay! Glad you got it working.
I consider The addition of the udev rule for the Brother device to 40-libsane.rules to have been necessary.
The copying of the files into the /usr/lib directory structure is necessary.
From https://sites.google.com/site/easylinuxtipsproject/15
Quote:
g. In 64-bit Linux Mint 18 and Ubuntu 16.04 the location for the supporting library files has changed, and the driver for the scanner feature doesn't always take that into account. The Brother driver puts them in /usr/lib64, whereas your operating system expects them in /usr/lib.
