From what you wrote, it sounded like you had not tried doing this. Okay, here's the relevant part of your log. This shows when the driver first failed, then it shows the driver being unloaded and reloaded with the quirk added: > [ 49.596314] xhci_hcd 0000:02:00.0: Command timeout > [ 49.596321] xhci_hcd 0000:02:00.0: Abort command ring > [ 61.128571] xhci_hcd 0000:02:00.0: Stopped the command ring failed, maybe the host is dead > [ 61.128575] xhci_hcd 0000:02:00.0: // Halt the HC > [ 61.151685] xhci_hcd 0000:02:00.0: Host not halted after 16000 microseconds. > [ 61.151695] xhci_hcd 0000:02:00.0: Abort command ring failed > [ 61.151698] xhci_hcd 0000:02:00.0: HC died; cleaning up > [ 61.151702] xhci_hcd 0000:02:00.0: xHCI host controller is dead. > [ 61.151722] xhci_hcd 0000:02:00.0: Timeout while waiting for setup device command > [ 61.354478] xhci_hcd 0000:02:00.0: Endpoint 0x0 ep reset callback called > [ 61.370472] xhci_hcd 0000:02:00.0: Ep 0x0: URB ffff881035fefc00 submitted for non-responsive xHCI host. > [ 61.370476] xhci_hcd 0000:02:00.0: Ep 0x0: URB ffff881035fefc00 submitted for non-responsive xHCI host. > [ 61.370478] xhci_hcd 0000:02:00.0: Ep 0x0: URB ffff881035fefc00 submitted for non-responsive xHCI host. > [ 61.370480] usb 2-1: device descriptor read/8, error -108 > [ 61.490469] xhci_hcd 0000:02:00.0: Ep 0x0: URB ffff881035fefc00 submitted for non-responsive xHCI host. > [ 61.490472] xhci_hcd 0000:02:00.0: Ep 0x0: URB ffff881035fefc00 submitted for non-responsive xHCI host. > [ 61.490474] xhci_hcd 0000:02:00.0: Ep 0x0: URB ffff881035fefc00 submitted for non-responsive xHCI host. > [ 61.490476] usb 2-1: device descriptor read/8, error -108 > [ 61.594469] xhci_hcd 0000:02:00.0: Endpoint 0x0 ep reset callback called > [ 61.594475] xhci_hcd 0000:02:00.0: xHCI dying or halted, can't queue_command > [ 61.594477] xhci_hcd 0000:02:00.0: FIXME: allocate a command ring segment > [ 61.594478] usb usb2-port1: couldn't allocate usb_device > [ 70.980103] random: nonblocking pool is initialized > [ 74.719104] bus: 'pci': remove driver xhci_hcd > [ 74.719111] xhci_hcd 0000:02:00.0: remove, state 4 > [ 74.719116] usb usb3: USB disconnect, device number 1 > [ 74.719118] device: 'ep_81': device_unregister > [ 74.719129] PM: Removing info for No Bus:ep_81 > [ 74.719143] bus: 'usb': remove device 3-0:1.0 > [ 74.719148] device: 'usb3-port4': device_unregister > [ 74.719155] PM: Removing info for No Bus:usb3-port4 > [ 74.719157] device: 'usb3-port3': device_unregister > [ 74.719163] PM: Removing info for No Bus:usb3-port3 > [ 74.719165] device: 'usb3-port2': device_unregister > [ 74.719170] PM: Removing info for No Bus:usb3-port2 > [ 74.719175] device: 'usb3-port1': device_unregister > [ 74.719185] PM: Removing info for No Bus:usb3-port1 > [ 74.719188] PM: Removing info for usb:3-0:1.0 > [ 74.719204] xHCI xhci_drop_endpoint called for root hub > [ 74.719206] xHCI xhci_check_bandwidth called for root hub > [ 74.719208] device: 'ep_00': device_unregister > [ 74.719217] PM: Removing info for No Bus:ep_00 > [ 74.719297] bus: 'usb': remove device usb3 > [ 74.719303] PM: Removing info for usb:usb3 > [ 74.719316] xhci_hcd 0000:02:00.0: // Halt the HC > [ 74.742402] xhci_hcd 0000:02:00.0: Host not halted after 16000 microseconds. > [ 74.742405] xhci_hcd 0000:02:00.0: Host controller not halted, aborting reset. > [ 74.742414] xhci_hcd 0000:02:00.0: USB bus 3 deregistered > [ 74.742426] device: 'usbmon3': device_unregister > [ 74.742519] PM: Removing info for No Bus:usbmon3 > [ 74.742531] device: 'usbmon3': device_create_release > [ 74.742539] xhci_hcd 0000:02:00.0: remove, state 1 > [ 74.742544] usb usb2: USB disconnect, device number 1 > [ 74.742546] device: 'ep_81': device_unregister > [ 74.742559] PM: Removing info for No Bus:ep_81 > [ 74.742574] bus: 'usb': remove device 2-0:1.0 > [ 74.742579] device: 'usb2-port1': device_unregister > [ 74.742588] PM: Removing info for No Bus:usb2-port1 > [ 74.742593] PM: Removing info for usb:2-0:1.0 > [ 74.742616] xHCI xhci_drop_endpoint called for root hub > [ 74.742618] xHCI xhci_check_bandwidth called for root hub > [ 74.742620] device: 'ep_00': device_unregister > [ 74.742631] PM: Removing info for No Bus:ep_00 > [ 74.742716] bus: 'usb': remove device usb2 > [ 74.742721] PM: Removing info for usb:usb2 > [ 74.742757] xhci_hcd 0000:02:00.0: // Disabling event ring interrupts > [ 74.742760] xhci_hcd 0000:02:00.0: cleaning up memory > [ 74.742763] xhci_hcd 0000:02:00.0: Freed ERST > [ 74.742765] xhci_hcd 0000:02:00.0: Freed event ring > [ 74.742768] xhci_hcd 0000:02:00.0: Freed command ring > [ 74.742773] xhci_hcd 0000:02:00.0: Freed segment pool > [ 74.742775] xhci_hcd 0000:02:00.0: Freed device context pool > [ 74.742777] xhci_hcd 0000:02:00.0: Freed small stream array pool > [ 74.742778] xhci_hcd 0000:02:00.0: Freed medium stream array pool > [ 74.742799] xhci_hcd 0000:02:00.0: xhci_stop completed -

It failed before the quirk could make any difference. Maybe you can put the quirk in /etc/modprobe.d so it will be used automatically. Add a line to /etc/modprobe.d/local.conf saying: options xhci_hcd quirks=0x00800090 and see if that makes any difference. If it doesn't, Mathias will have to suggest something else for you to try.
