A peripheral device comprises a first entity and a second entity. In operation, the first/second entities are configured to respectively: receive a first/second entity-related message from at least one other device to indicate the availability of the at least one other device for attachment, send, to the at least one other device, a first/second entity-related message indicating the availability for communication with the at least one other device, receive, from the at least one other device, a first/second entity-related signal including a first/second entity-related peripheral device identifier, send a first/second entity-related response to the at least one other device, receive, from the at least one other device, a first/second entity-related device response, and send, to the at least one other device, a first/second entity-related second peripheral response including the first/second entity-related peripheral device identifier.
