Subject: Input: keyboard/Trackpad support for MacBookPro 12,1

My new MacBook Pro (Retina, 13-inch, Early 2015, Model Identifier: MacBookPro12,1) with ForceTouch
trackpad has a new Product ID 0x0273, which I think is the ISO, and the other should be ANSI:0x0272,
JIS:0x0274, but I'm not sure, anyone can confirm this?
Apple Internal Keyboard / Trackpad:
Product ID: 0x0273
Vendor ID: 0x05ac (Apple Inc.)
Version: 6.22
Serial Number: xx
Manufacturer: Apple Inc.
Location ID: 0x01000000

However, after I add the Product ID as usual, the keyboard works fine, but the trackpad doesn't work
at all, after checking the Info by lsusb, the trackpad seems to fallback to the old geyser way because
it reports a wMaxPacketSize 0x0040 1x 64 bytes, I don't have much knowledge about trackpad
driver, is there anyone that can figer out what the driver protocol is?
