In general this is a bad/risky thing to do from a driver. In UEFI drivers are
designed to be simple and policy choices are moved into the platform.
In the fast boot case only drivers needed to boot will be started, so the USB
storage device may not even be available. So there can be performance and
stability issues if you driver pokes around the system and tries to read/write
to a usb storage device. Hopefully you are just doing this to debug some
problem….
