I think this indicates either a problem in the SCSI layer or a synchronization error in usb-storage. It's an indication that the SCSI link to usb-storage is still in use even after we unregistered our driver -- probably because we're in the middle of error recovery. It's not worth worrying about now, although later we might want to look at it more closely.
