bus	the Joybus instance to use
response	buffer to store the origin state response in

Returns

0 on success, a negative joybus_error on failure

joybus_gcn_calibrate_async()

int joybus_gcn_calibrate_async	(	struct joybus *	bus,
		struct joybus_gcn_controller_state *	response,
		joybus_transfer_cb	callback,

response	buffer to store the identity response in
callback	a callback function to call when the transfer is complete
user_data	user data to pass to the callback function

Returns

0 if the transfer was started, a negative joybus_error otherwise
