I'm currently developing with an Xbox One Thrustmaster TMX wheel, if
we don't perform at least some perfunctory FFB initialization of this
nature (or indeed if no DirectInput application is running) then the
wheel exhibits considerable resistance, similar to that of a stationary
car. Changing cf.lMagnitude to a nonzero value does cause the wheel to
continuously turn in the given direction with the given force as one
would expect (max magnitude per DirectInput docs is +/- 10000).
Failure here is non-fatal, we log any errors and move on.
