This motherboard advertises it has 1 x 5Gb/s USB Type C port (@back panel) support 3A power output

But I don't notice any change in the charging speed.

I have noticed that a specific Asus software for USB charging exists, but I'm on GNU/Linux and it's only for Windows (what a surprise!)

Does anybody know how to configure this fast charging/3A power output? I don't want to install Windows just for this function.
