But it's there both with and without the feature enabled: /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M | Port 4: Dev 10, If 0, Class=Hub, Driver=hub/7p, 5000M |__ Port 2: Dev 11, If 0, Class=Vendor Specific Class, Driver=r8152, 5000M This feature is only for convenience and should never prevent the network from working.
