Abstract
A detection control device including a USB connection port, a first detection circuit, a second detection circuit, a control circuit, a first switching circuit and a second switching circuit is provided. When a first pin group of the USB connection port is coupled to an external device, the first detection circuit generates a first detection signal according to a first time constant. When a second pin group of the USB connection port is coupled to the external device, the second detection circuit generates a second detection signal according to a second time constant. The control circuit generates a first control signal and a second control signal according to the first and second detection signals. Each of the first and second switching circuits communicates with the external device via the first or second pin groups according to either the first control signal or the second control signal.
