In that case better to make connections to the place where D+/D- are together :approve:
So you are not going to use a STF201-22 IC at all, right?

Right - I will be sticking a couple of zener diodes on the USB lines. I need to check the voltage specs to see what zener voltage I'll need.
I'm not worried about protecting them too much as they will only be connected through the sync connector to the USB hub interface which has its own protection.
