IMHO this is interesting and it can help. Unfortunately it is not an 
answer; it rather points to start looking to a different direction, i.e. 
BIOS. Even though the USB trackball is detected within Ubuntu Mate when 
executing the |lsusb| command, the trackball misbehaves probably due to 
an issue with BIOS. Please check the output of the following command, 
especially the lines at the end.

(note: info related to Logitech trackball is on 
/sys/bus/usb/devices/2-1.2 path)
