I have found the multitouch initialization sequence for the Synaptics V7.4 Clickpad touchpad in my HP dv7t Select. The touchpad uses a new 12 byte protocol for multitouch events after it has been properly initialized. I have not completely figured out the new multitouch protocol. I would imagine that the initialization sequence and multitouch protocol for the Synaptics V7.2 touchpads is similar if not the same as the V7.4 touchpads.
