I mean that we could implement this on top of setupapi routines instead
of essentially reimplementing them here. I know that it's
architecturally upside-down, but we call call user-mode functions
elsewhere in ntoskrnl, and as long as we're going to keep drivers in
user-mode I don't see any reason to avoid that.
