Trisquel 7.0 Belenos
tested with the following kernel libre:
Linux-libre 3.13.0-121-lowlatency
does it work with free software?
yes
free driver used:
xhci_hcd
Description:

Hundreds of hardware devices are using Linux Foundation 3.0 root hub. We need to list at least one hardware here to demonstrate which driver that is used.

Intel Z270 chipset

Intel Z270 is the current leading chipset on the market. Any mainboard with this chipset should be able to run USB 3.0 on a free GNU/Linux distro as far as I know: I've tried Gigabyte GA-Z270-Gaming K3 (rev. 1.0) and ASUS ROG STRIX Z270H GAMING with success.

Gigabyte GA-Z270-Gaming K3 (rev. 1.0)
I just list one of the USB 3.0 devices and its connected USB controller here to make the list short and concise.

I confirm that I can use USB 3.0 speed on this hardware device (USB read and write speed tests performed on the USB 3.0/2.0 ports). I have not tried USB 3.1 yet!
