Apart from the board and some disks and memory the computer has no other hardware. The board has four usb 3.0 ports on the back. Using any of those ports, with my USB 3.0 hub, with my phone triggers a swarm of messages like this: xhci_hcd 0000:00:14.0: xHCI xhci_drop_endpoint called with disabled ep ffff880354156900 If I connect the 3.0 hub via USB 2.0 hub instead, or use the 2.0 hub directly all of the problems go away.
