The USB 2.0 ports on this board work but they don't 'initialize' the device that's being plugged in. Like when you plug in a USB thumb drive it doesn't pop up on the windows 10 screen with the usual options. It also doesn't show up when going to eject. It does show up under 'this pc' and that's the only way to eject. I noticed this on the Gigabyte X370 boards I've had also. anybody else notice this ?
