Abstract
A USB detecting method for use with a controlling and processing unit, a USB input/output port, at least one switch and at least one USB peripheral device is provided. The at least one switch is arranged between the controlling and processing unit and the USB input/output port and/or arranged between the USB input/output port and the at least one USB peripheral device that is electrically connected with the USB input/output port. Firstly, a USB detection signal of the at least one USB peripheral device is provided to the controlling and processing unit. According to a result of receiving the USB detection signal, the controlling and processing unit determines whether the switch is reset. For resetting the at least one switch, the controlling and processing unit simulates the action of plugging and pulling out the USB peripheral device.
