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

[h1]Intel Z270 chipset[/h1]
[p]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.[/p] know: I've tried Gigabyte GA-Z270-Gaming K3 (rev. 1.0) and ASUS ROG STRIX Z270H GAMING with success.[/p]

[h2]Gigabyte GA-Z270-Gaming K3 (rev. 1.0)[/h2]
I just list one of the USB 3.0 devices and its connected USB controller here to make the list short and concise.

[p]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![/p]
