If its a kernel issue any idea about which specific mailing list
or person to contact?

Since Xorg reported this:

  (II) config/udev: Adding input device AVAGO TECHNOLOGIES AVAGO USB OFN Device (/dev/input/event3)
  (**) AVAGO TECHNOLOGIES AVAGO USB OFN Device: Applying InputClass "evdev pointer catchall"
  (**) AVAGO TECHNOLOGIES AVAGO USB OFN Device: Applying InputClass "evdev keyboard catchall"
  (**) AVAGO TECHNOLOGIES AVAGO USB OFN Device: always reports core events
  (**) AVAGO TECHNOLOGIES AVAGO USB OFN Device: Device: "/dev/input/event3"
  (II) AVAGO TECHNOLOGIES AVAGO USB OFN Device: Found 3 mouse buttons
  (II) AVAGO TECHNOLOGIES AVAGO USB OFN Device: Found scroll wheel(s)
  (II) AVAGO TECHNOLOGIES AVAGO USB OFN Device: Found relative axes
  (II) AVAGO TECHNOLOGIES AVAGO USB OFN Device: Found x and y relative axes
  (II) AVAGO TECHNOLOGIES AVAGO USB OFN Device: Found keys
  (II) AVAGO TECHNOLOGIES AVAGO USB OFN Device: Configuring as mouse

  (II) config/udev: Adding input device AVAGO TECHNOLOGIES AVAGO USB OFN Device (/dev/input/mouse0)
  (II) No input driver/identifier specified (ignoring)

Is that last line significant?

I ran "evtest /dev/input/event3" which output this:

  Input driver version is 1.0.0
  Input device ID: bus 0x3 vendor 0x192f product 0x0 version 0x101

      Event code 273 (RightBtn)

    Event type 20 (Repeat)


Yes, relative X/Y in the mouse section about is suspicious.
