My dmesg is still being spammed with these messages: [ 260.043673] usb 2-1: Device not responding to setup address. [ 260.246918] usb 2-1: device not accepting address 15, error -71 [ 260.633662] usb 2-1: new high-speed USB device number 17 using xhci_hcd [ 261.341340] usb 2-1: USB disconnect, device number 17 I guess it's safe to assume at this point that this is a hardware problem?
