You have been subscribed to a public bug: I have a Jelly Comb mouse, connected with a wireless USB dongle. It has two main buttons, a clickable scrollwheel, and another button behind the scrollwheel.
XEV does not detect clicks from the scrollwheel, or the additional button behind the scrollwheel. Attached is a xev report where all the buttons are activated. Button 1 is left click, Button 3 is right click, Button 4 is scroll up and Button 5 is scroll down. I am using Ubuntu 20.04.2 LTS xmodmap-pp gives the following: There are 10 pointer buttons defined.
