Any controller that contains either a USB or SDIO card would have a bootstrap loader, available when the controller is in safe mode, that would allow the controller to be loaded up to operational status (OS, Drivers, RTEXE, etc...) from a deployment image contained on the removeable media. This would allow a replacement controller to be unboxed and installed in a stand alone system without the need to install software from a development computer.
This is one of those things that sort of bridges between a hardware and software request.
