摘要： The present disclosure provides an electronic device having a USB interface and a method for starting USB communication with such an electronic device, so as to solve the problem of a risk of damaging a mobile phone terminal device arising from sharing of an interface by a charger and a USB communication cable in the related art. In the electronic device, a port GPIO of a baseband chip is connected to a pin USB_VBUS of a USB interface of the baseband chip; based on this circuit, a power management chip detects a state of plugging-in-or-pulling-out of the charger and generates a corresponding interrupt request; and the baseband chip controls the GPIO to output a corresponding level according to the interrupt request. By connecting the port GPIO and the pin USB_VBUS and controlling an output level of GPIO with a software, a high level or a low level (as a triggering signal for starting or terminating the USB communication) is input to the pin USB_VBUS, thus avoiding damage to the device.
摘要翻译：本公开提供一种具有USB接口的电子设备和用于开始与这种电子设备的USB通信的方法，以解决由于充电器共享接口而导致的移动电话终端设备损坏的风险的问题，以及相关技术中的USB通信电缆。在电子设备中，基带芯片的端口GPIO连接到基带芯片的USB接口的引脚USB_VBUS; 基于该电路，电源管理芯片检测充电器插拔的状态，并产生相应的中断请求; 并且基带芯片控制GPIO根据中断请求输出相应的电平。通过连接端口GPIO和引脚USB_VBUS并通过软件控制GPIO的输出电平，将高电平或低电平（作为用于启动或终止USB通信的触发信号）输入到引脚USB_VBUS，从而避免损坏到设备。
