Abstract
An electronic unit includes a USB host and a USB device. After the USB host and the USB device are connected to each other by a USB cable, a signal requesting for a connection permission is transmitted from the USB device to the USB host, and the USB host determines whether to permit a connection based on the signal. The electronic unit further includes a power supply configured to supply power to the USB device, and an additional GND pattern different from a GND pattern of the USB cable is electrically connected to a GND of the USB port of at least one of the USB host and the USB device. An area of the additional GND pattern is 2000 mm2 or more.
