Delegated and distributed responsibility. Windows makes the hardware vendors implement it in the their device drivers, and the "system integrator" (laptop manufacturer) is responsible to verify that it works. The laptop manufactures (a) have a limited and known set of hardware to verify works and (b) have "leverage" (i.e. promises to purchase large quantities of peripherals) to ensure the hardware vendors fix any problems found. Linux drivers don't get much hardware vendor love.
