I'm facing the same problem with both my laptop (Lenovo G500s) and Desktop (AMD FX 9590, Asus M5A 99FX). USB 3 hard drive doesn't work with USB 3 port, but any other combination works.
USB3 > USB3 = Doesn't work
USB3 > USB2 = Works
USB2 > USB3 = Works
USB2 > USB2 = Works
I never tried a USB 3.0 device before, right now I'm using Ubuntu 16.04 LTS.
