So I've got the system up and running correctly now.
I did call Microsoft tech support and they were no help at all. In fact, when they called aback a second time, it was a little sketchy what they were asking me to do, so I told them I'd fix it myself. I couldn't even get a toll free number for gigabyte.
Eventually, I reinstalled the OS for a third time and used only the drivers on the motherboard disc and installed Windows Updates slowly, a few at a time. Eventually I ran into a different error and one of them failed to install. I used a Windows Update readiness tool and installed that after the failure. After that, all updates went through properly and the issues with the USB3 hub never showed up (knock on wood).
Did you check the data and power cables were connected properly on both ends?
Did you check in disk management to see if it was recognized there?
Right click My Computer and select "manage"
Find "disk management" on the left and select it
See if your drive appears there and if it does, maybe it needs to be partitioned?
