In a process for loading firmware via a hub into a group of interconnected control devices, a set of communication frames is transmitted by the hub and addressed to at least one of the control devices in the group for reaching all of the interconnected control devices therein. First and second inquiries regarding validity and invalidity respectively of the set of frames are sent collectively to the group, and based on replies from any of the control devices that have received at least one of the inquiries, the set of frames is re-transmitted or a successive set of frames is transmitted or loading of the firmware is aborted, the process being repeating all portions of the firmware are loaded.
