Only this laptop had been confirmed is ALPS: 0102 – FF02 trackpoint, it
return 0 of extended button.
I saw the other device that returned 0, but don't have it now, so the ID
can not be checked.

ThinkPad always have 3 buttons installed, I suggest always set 0x33 for
button info when the button info returned 0.
