Public bug reported:

Connecting an USB disk on an USB port is OK the fisrt time,
but if I disconnect then reconnect the same disk on the same USB port it fails.

During the second connection, the following message appears  in /var/log/syslog :
    usb 3-9: reset high-speed USB device number 10 using xhci_hcd
and device number seems to be incremented at each connection
