Boot Camp Assistant makes it possible to install and run Windows operating system on Mac computers without using any virtualization software. One needs to install required Boot Camp support software or drivers to make sure that keyboard, touchpad, displays and other components of Mac computer work great with Windows operating system.
Any mac device that works in Bootcamp, you could probably extract drivers from the bootcamp package.
