Thanks, Kai-Heng. I've installed linux-oem-20.04 and selected the new kernel, 5.6.0-1052-oem, on boot. Unfortunately the behavior is identical. The mouse still appears as "PS/2 Logitech Wheel Mouse" with all the same information (e.g., event3 in xinput). I checked dmesg and the four lines you identified are still there with the OEM kernel:
