The number of buttons is a constant set up when the device is created (it would be a QOM property if this device had been converted to QOM; as it is it's an argument to the stellaris_gamepad_init() function) and the num_buttons field itself is not migrated. As it happens the one caller of this function passes the constant value "5"... thanks -- PMM
