Has this been resolved in the meantime?
According to the SBP-2 and SBP-3 specs, there has to be at least one
logical unit. So, if it is desirable to establish target instances
without having a logical unit during the entire lifetime, then the
implementation would have to keep this target invisible to the external
bus for as long as there is no logical unit. There should be no SBP-2/
SBP-3 unit directory in the 1394 Configuration ROM without at least one
logical unit entry.
