Abstract
A communication system includes a host device and a peripheral device which are communicate with each other according to a main communication protocol that allows the command to be transmitted only from the host device to the peripheral device. The peripheral device accepts an input and to generate a trigger that urges the host device to start a target communication event in accordance with the input. The host device issues a trigger report request command to the peripheral device. The peripheral device transmits trigger generation report information containing a presence or absence of a generation of the trigger to the host device in response to the trigger report request command. The host device receives the trigger generation report information, determines the presence or absence of the generation of the trigger and starts the target event if the presence of the generation of the trigger is determined.
