Title:
  [Dell XPS 15 9500] New touchpad detected as "PS/2 Logitech Wheel
  Mouse"

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I've been using Ubuntu 20.04 on a Dell XPS 15 9550. The laptop's
  touchpad had a hardware defect common to the model (nicknamed
  "wobble") so Dell sent a tech to replace it. The new touchpad looks
  identical to the original but the kernel doesn't correctly detect it.
  The device does work, but appears to the kernel as a "PS/2 Logitech
  Wheel Mouse," which prevents the use of features like two-finger
  scrolling, disabling tap to click, and palm detection.

  A good summary of my troubleshooting steps are here:
  
https://askubuntu.com/questions/1330555/touchpad-detected-as-ps-2-logitech-wheel-mouse-dell-xps-15-ubuntu-20-04

  Importantly, I've tried a mainline kernel downloaded from Ubuntu
  (5.11.12 and a 5.12.0 release candidate, whereas the current version
  is a 5.8.0). I've also tried two bootable USB drives containing Ubuntu
  20.04 and 21.04 (release candidate). Nothing has changed the device
  detection or behavior. The issue is identical in the default Ubuntu
  desktop and in Plasma. There are no touchpad settings in the UEFI
  BIOS.

  Per the touchpad detection instructions, I've attached the output of 
/proc/bus/input/devices, Xorg.0.log, and the `xinput --list` command. My 
suspicion is that Dell has ordered a brand new touchpad model for which there 
is no kernel driver; looking at the logs, the previous model was an elantech, 
but I'm not sure if the new one is as well.
