[AceLan Kao]

Hi,

Please refer the test result on bug 1305522[1]
Thanks Kent Baxley's help, there are 5 machines tested.
2 machines with i2c touchpad
   1. Dell XPS 13
   2. Dell Inspiron 5547
and 3 other machines with PS/2 touchpad
   1. Dell XPS 15
   2. Dell E5440
   3. Dell Inspiron 3137
All of them works well and pass the test.
