The solution proposed by Juan Hernandez (message 32) worked for me. I am running Xubuntu 16.04 on a Dell Inspiron 3542. I finally decided to look for a fix after successfully using a wireless mouse for some time. I did not have to modify /usr/share/X11/xorg.conf.d/90-libinput.conf as some others did.
