Abstract
A charging-cable includes a charger-connector for connecting the charging-cable to a USB connector in a charger, and a device-connector for connecting the charging-cable to a portable device. The charger-connector includes USB-terminals arranged so that a first USB-terminal can connect to the VBUS signal, a second USB-terminal can connect to the D− signal, a third USB-terminal can connect to the D+ signal and a fourth USB-terminal can connect to the ground signal of a USB connector. The device-connector includes device-terminals connected to the portable device so that a first device-terminal connects to a ground terminal and a second device-terminal connects to a charging terminal of the portable device. Moreover, the first USB-terminal is connected to one of the second or third USB-terminals via a first circuit. Furthermore, the other of the second or third USB-terminals is connected to the second device-terminal via a third circuit.
