USB 3.1 Generation 2 is becoming a more common standard that runs at double of what USB 3.0 does.
The Shuttle still runs at 3.0 (aka 3.1 gen 1) even if you have a host controller capable of running on 3.1 gen 2. I mean, just because you upgrade to a 10 gigabit NIC doesn't mean your switch gets any faster…
Personally, I'm pretty much convinced the USB chipset has nothing to do with it. I've run my Shuttle, and also the sister SDI product UltraStudio, on a variety of machines (desktop and laptop) with no issues at all. However, it has problems with USB link power saving; Linux turns the power saving off when it sees the Shuttle's USB ID, and that's the end of it. My assumption would be that the reason why Renesas makes a difference for Windows users has something to do with that (ie., simply different drivers that implement power saving differently or not at all); I've never bothered to try to find out, though.
