It should be noted that, when a data transmission link exists between the USB host and the USB device, a lock signal, i.e. an occupied signal, is generated to indicate that a data transmission relationship exists between the USB host and the USB device, and the data transmission relationship is occupied. Therefore, before establishing a data transmission link between the target USB host and the target USB device, it is required to determine whether the target USB host has a data transmission relationship with other USB devices (i.e. a first occupation signal exists), and whether the target USB device has a data transmission relationship with other USB host (i.e. a second occupation signal exists), and meanwhile, the current USB host/USB device may be prompted to be occupied through a program control interface of the server or a program control interface of the network device.
