Also can you explain the touchpad ID thing a little bit more? What exactly does this denote? When I mask the values like it says with 0x7F I get 35 for touchID 1 and 15 for touchID 2.

The Touch ID byte switches values depending on whether a finger touch is active. The value will be between 0-127 when a touch is active; the value will be between 128-255 when no touch is detected (active + 128). The value increments by 1 on each active touch.

The Touch 2 ID will change when the controller detect a second touch.
