Devices (targets in SCSI-speak) do not send unsolicited messages, ever.
While it would be trivial to scan for newly attached devices even from
user space (parse /proc/scsi/scsi, try to add each device not already
present, repeat), the detection of devices gone missing might be more
difficult without kernel support.
