My Passport Ultra 2TB Not Recognized in Windows 8.1 with USB 3.0

The hub arrived today and I am happy to report that the 2TB My Passport Ultra does work in the USB 3.0 ports when connected through the hub. It’s recognized by the PC with 3.0 transfer rates. I’m still not sure what the problem is though. Too much or too little power, or something else? I spent an extra $40 for the hub (probably should have bought a cheaper one), but I needed the hub anyway so I’m not really mad about it. I’m just glad I can use the drive with USB 3.0 now.
