I have a box that's having its dmesg flooded with..
hub 1-0:1.0: over-current change on port 1 hub 1-0:1.0: over-current change on port 2 hub 1-0:1.0: over-current change on port 1 hub 1-0:1.0: over-current change on port 2 hub 1-0:1.0: over-current change on port 1 hub 1-0:1.0: over-current change on port 2 hub 1-0:1.0: over-current change on port 1 hub 1-0:1.0: over-current change on port 2 hub 1-0:1.0: over-current change on port 1 hub 1-0:1.0: over-current change on port 2 hub 1-0:1.0: over-current change on port 1 hub 1-0:1.0: over-current change on port 2
over and over again.. The thing is, this box doesn't even have any USB devices connected to it, so there's absolutely nothing I can do to remedy this.
lsusb -v output below
