Can't connect by USB (BBBlue)

So I just got a Beaglebone Blue and have been trying to follow the getting started directions with no luck.

I flashed the 9.4 IoT 2018-06-17 build to a card and that does boot it up. Blinking lights blink away and I can connect to its WiFi. I can also SSH in via the address and the cloud9 interface works.

However, over USB nothing happens. I don’t get a new network interface when I connect it, nothing seems to install, and nothing new shows up in device manager (not in network adapters or other devices). I’ve tried two win10 computers and different cables. Flipping through some other posts on various sites, tried installing BONE_D64 driver to see if it would magically find something but no luck.

Any thoughts on where to go from here?
