NUC’S USB ports embedded are 3.0 there is not an option to disable them, it is necessary to add the USB 3.0 driver into the image of your OS before the installation process; for example Windows® 7.

I don't believe one can install drivers in the OpenBSD implementation without causing unintended consequences. I'm not even sure how I would really go about doing it without major surgery.
I broke down and installed FreeBSD and have had it working for a couple weeks now. I'd much prefer to have OpenBSD on it as I've used OpenBSD for years.
