The invention relates to a device control method and apparatus. The method comprises the steps of when an abnormal communication connection between a terminal and a server is monitored, obtaining a device identifier of the terminal; according to the device identifier, obtaining device node information pre-mapped to the server by the terminal; and according to the device node information, activating a normal communication connection between the terminal and the server. According to the device control method and apparatus, when a manufacturer performs batch testing on a USB device by utilizing the server and the abnormal communication connection between the USB device and the server occurs, the normal communication connection between the USB device and the server can be quickly re-established, so that the interruption of USB device testing caused by the abnormal connection is avoided and the influence on normal batch testing of the USB device is avoided.
