Abstract
Systems and methods are disclosed, including a USB interface detector, a detection method, a USB connector, and an electronic device. The detection method may be applicable to the USB connector mounted in the electronic device. According to an operation mode of the electronic device, a first pin and a second pin in the USB interface can be pulled up or pulled down. After the pull up or the pull down, a voltage change at the first and second pins are detected. If the voltage changes cross a reference voltage, an instruction related to attachment or detachment with a second device can be provided.
