Other USB devices (memory sticks, Wi= Fi, Bluetooth) do not trigger the warning: https://lore.kernel.org/netdev/2a436486-a54d-a9b3-d839-232a38653af3@gmail.c= om/ Curiously, the above-linked other reports seem to indicate that the warning occurs when connecting USB hubs. It's unclear what those have in common with the LAN9514. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
