Unfortunately, due to the current design of the PixArt touchpad hardware and FW, our single packet data width needs 11 bytes/15 bytes to receive three-finger/four-finger data in absolute coordinate mode. Obviously, it exceeds the design of the native driver, and we try to extend the length of a single data packet to 16 bytes in patch(1/2). I apologize that this radical change may not be the best way to go, and I will try to rewrite this section if there are better suggestions. Thanks.
