As Jun Li helpfully explained my patch is not correct, so don't bother.
I don't have a problem with your patch, was just trying to share what I had done.
I've since learned that the board I'll be working on will not even have SS, so I will not pursue SBU. I'll most likely use your patches instead as they seem simpler than what I did and should fully meet my needs for an usb port that works in both host and device mode.
Not that it matters, but +1 from me on applying your patches. (If people are hesitant to do it because of lack of SS, then maybe that could be adressed by adding a comment setting the expectations?)
