Description

TECHNICAL FIELD The present disclosure relates to an aerosol generation device and a power supply unit for an aerosol generation device. BACKGROUND ART PTL 1 describes a method for controlling a USB controller, the method including a step for detecting a level change in an ID pin of a USB socket via a GPIO, the GPIO being connected to the ID pin and being used for detection, and a step for controlling the USB controller to turn on when it is determined that the ID pin of the USB socket has changed from a high level to a low level. PTL 2 describes a USB device suitable for interconnection with a USB host having a D bus that is coupled to ground via a pull-down resistor, the USB device including a microcontroller that has a first port and a second port, and the first port being coupled to a voltage source via a resistor, and a switch that is operated by the microcontroller via the second port to selectively interconnect the first port with the bus of the USB host. PTL 3 describes an interface identification circuit in which: a first detection module is used to acquire a first voltage in accordance with a VBUS pin voltage of a USB interface and output the first voltage to a control module; the first voltage is used to indicate whether the VBUS pin voltage of the USB interface is at a high level or a low level; and the control module is used to determine the connection state of the USB interface in accordance with the first voltage, and output a prompt message if it is determined that the connection state of the USB interface is a connection to a main device. CITATION LIST PATENT LITERATURE PTL 1 CN 109766288 APTL 2 EP 2687993 A1PTL 3 CN 213402973 U SUMMARY OF INVENTION TECHNICAL PROBLEM If the control portion is connected to an external device and a high signal is output to the control portion when power-supply power is not being supplied to the control portion, the control portion may malfunction.
