Comment 21 for bug 349767

Additional comment:

After the device has failed:
1. device is not listed with "lsusb" any more
2. every call of "lsusb" produces four lines with increasing adress numbers like these in /var/log/messages:
May 11 17:12:22 user-laptop kernel: [ 7402.560103] usb 6-1: new full speed USB device using uhci_hcd and address 10
May 11 17:12:23 user-laptop kernel: [ 7403.176101] usb 6-1: new full speed USB device using uhci_hcd and address 11
May 11 17:12:23 user-laptop kernel: [ 7403.736083] usb 6-1: new full speed USB device using uhci_hcd and address 12
May 11 17:12:24 user-laptop kernel: [ 7404.312110] usb 6-1: new full speed USB device using uhci_hcd and address 13

Several strange CPU state udev REMOVE and ADD events happen, during the drive failure.
See appended log for details.

Kind regards,
