You seem to be over thinking this.  Is there any reason to believe that
setting STALL doesn't have the overall desired effect?  If you get a packet
with the wrong toggle, then something else is already wrong.  Does it reall=
y
matter which the SIE sends back for that?  Presumably the next packet will
have correct toggle and stall will be sent back.
