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. -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
