Feel Sorry for you about your usb drive card.
I know this card is recommend from oculus, but from my experience total overvalued. I just got a 7 slot usb 3.0 hub. Its really important that its a active one with power supply. So if you have 2 usb 3.0 but the hub in one of them and the oculus (cause i think it needs the most bandwith) in the mainbord slot.
I have all my 3 sensors, 4 External Harddrives connectet to my hub. The games are running from the external harddrives and i have zero issues. Its just plug and play, tracking works absolutely fine.
Maybe thats helps you to increase your experience!
