As an additional note: since that problem I could not mount any other mass storage device (even usb keys): [ 8963.471154] xhci_hcd 0000:00:14.0: Timeout while waiting for a slot [ 8963.471159] hub 2-0:1.0: couldn't allocate port 11 usb_device [ 8995.002796] xhci_hcd 0000:00:14.0: Timeout while waiting for a slot [ 8995.002803] hub 2-0:1.0: couldn't allocate port 11 usb_device So I did a "rmmod xhci_hcd": [ 9057.543485] xhci_hcd 0000:00:14.0: remove, state 4 [ 9057.543491] usb usb3: USB disconnect, device number 1 [ 9057.543659] xhci_hcd 0000:00:14.0: USB bus 3 deregistered [ 9057.543665] xhci_hcd 0000:00:14.0: remove, state 1 [ 9057.543669] usb usb2: USB disconnect, device number 1 [ 9057.543671] usb 2-3: USB disconnect, device number 2 [ 9057.850472] usb 2-4: USB disconnect, device number 3 [ 9057.994823] xhci_hcd 0000:00:14.0: USB bus 2 deregistered Then I had to log from another computer (usb keyboard ^^) to modprobe xhci_hcd again. I don't know how much of this log may be interesting but the general idea below is that USB keys can be mounted again. [ 9379.258224] systemd-logind[2280]: New session 25 of user adrien.
