Public bug reported:
It looks an old bug report (#1581088) is back.
I recently upgraded from 18.1 to 18.2 and lost my middle mouse button of a
Bluetooth Mouse
"Logitech M557"
Searching for root cause I found this bug report #1581088.
Following resolution attemps I could figure the same root cause and solution.
After upgrade :
>> xinput list-props 12

my middle mouse button is working as expected.
May be worth to mention:
I'am running the following kernel:
>> uname -r
