A communication method performed by a primary communication device having a communication initiative through a bus, the method comprising:

• communicating with a plurality of secondary communication devices, wherein the plurality of secondary communication devices are configured to perform communication under control of the primary communication device;
• causing the primary communication device to assign a respective dynamic address to each of the plurality of secondary communication devices;
• causing the primary communication device to acquire a respective capability information from at least one of the plurality of secondary communication devices;
• and
• causing the primary communication device to assign a respective group address to at least one of the plurality of secondary communication devices and to set the respective group address in the at least one of the plurality of secondary communication devices.

A communication system comprising:

• a primary communication device having a communication initiative, through a bus;
• and
• a plurality of secondary communication devices configured to perform communication under control of the primary communication device, wherein
• the primary communication device includes:
• communication circuitry configured to communicate with the plurality of secondary communication devices, and
• control circuitry configured to:
