Re: USB 3.0 Hub
Wish you the best of luck -- you're liable to need it!
I've had problems with USB 3.0 working properly on my desktop -- and was only able to fix that when I scrounged a firmware update for the Sony Renesas chipset which, of course, could ONLY be applied in MS Windows. After that I got reliable performance in both Windows and Ubuntu.
So, if the hub doesn't work well (you get USB 2 speeds instead of USB 3), you might be up against the same problem.
Ubuntu 15.04 Mate, Mint 17.1; MS Win 8.1, Win10 TP.
Will not respond to PM requests for support -- use the forums.
