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： An implementing method for matching the frequency bands of the mobile terminals, a mobile terminal, and a mainboard thereof are disclosed. The mobile terminal involves a signal transmitting/receiving module with at least two frequency bands, a radio-frequency transmitting module, a radio-frequency receiving module and a radio-frequency front-end module. The mobile terminal further involves a first connection selection module and a second connection selection module. The implementing method for matching the frequency bands of the mobile terminals comprises the following steps. The multi frequency bands bonding pad compatibility is achieved respectively on the circuit board by the radio-frequency transmitting module, the radio-frequency receiving module and the radio-frequency front-end module. When the mobile terminal has to work within a certain frequency band, one end of the first connection selection module is connected with the transmitting pin of the frequency band in the signal transmitting/receiving module, and the other end is connected with the radio-frequency transmitting module. One end of the second connection selection module is connected with the receiving pin of the frequency band in the signal transmitting/receiving module, and the other end is connected with the radio-frequency receiving module. The radio-frequency front-end module is connected with the radio-frequency transmitting module and the radio-frequency receiving module.
