The is a code in place that tried to recover too old dSMs by making them visible in the UI, which then told the user that the dSM needs to be updated.
This code no longer worked, because attempts were made to ask more data from the dSM which kept failing due to bus api errors.
To work around this problem, just tell the system that this is a dSM11 but don't try to talk to it any further. This is enough to make it visible in the dSS and thus make it show up in the UI too.
