9 introduced on 4th generation devices (Surface Pro 4, Surface Book 1), but
17 Not much is currently known about SAM on 4th generation devices (Surface Pro
18 4, Surface Book 1), due to the use of a different communication interface
19 between host and EC (as detailed below). On 5th (Surface Pro 2017, Surface
20 Book 2, Surface Laptop 1) and later generation devices, SAM is responsible
