Other then the Reset pin method there is no other way to reset the superhub to defaults without logging into it.
A call to the Tech support line and thay may be able to do it for you. (Indian call center agent love to default reset the SH) Thay did it to mine once without my permission for a fault that a full rest would not have helped.
