Interesting. I would try to go back to the state where everything was working and see if that solves things. Maybe the hub was down clocking to USB 2.0? I believe I've primarily been testing with a USB 2.0 port as I'm too lazy to get to the back of my desktop where the 3.0 ports reside. I can try that this evening though. We might be on to something as I believe my tablet only exposes a 2.0 or maybe even 1.1 port (downloads were very slow...but that could also have been the star analysis on the SGP side)
Thanks,
Jared
