Further, according to the data communication relationship between the target USB host end and the target USB device end, a data transmission link is established between the target USB host end and the target USB device end, including:
when the target USB host end has a data communication relation with other USB equipment ends and/or the target USB equipment end has a data communication relation with other USB host ends, sending a communication disconnection instruction to ensure that the target USB host end and the target USB equipment end have no data communication relation with other USB equipment ends and other USB host ends;

It should be noted that the other USB host terminals refer to all USB host terminals on the server except the target host terminal, and the other USB device terminals refer to all USB device terminals on the server except the target device terminal.
It should be noted that, as shown in fig. 3, before a data transmission link between the USB host end a and the USB device end a is established, the network side device may first determine whether the USB host end a is online (for example, whether the USB host end a is online may be determined by the server itself, when the server is in normal use, it indicates that the USB host end or the USB device end is online, or manually determines that the determination condition may be set according to an actual condition), if the USB host end a is not online, an error code is returned, the operation of establishing the data transmission link is suspended, if the USB host end a is online, it is determined whether the USB host end a has a data communication relationship with other USB device ends (for example, there is a data communication link), and if so, a communication disconnection instruction is sent, so that the USB host terminal A disconnects the data communication relation with other USB equipment terminals, if not, the source Mac address (02-a0-AC-10-82-04) of the USB device terminal a is sent to the USB host terminal a, and it is determined whether the USB device terminal a is online, if the USB device terminal a is not online, an error code is returned, the operation of establishing the data transmission link is suspended, if the USB device terminal a is online, then, it is determined whether the USB device side a has a data communication relationship with other USB host sides (for example, a data communication link exists), if so, a command of disconnecting communication is sent out, so that the USB device end A disconnects the data communication relation with other USB host ends, if not, the source Mac address of the USB host terminal a is sent to the USB device terminal a (02-a0-AC-10-81-01), so as to establish a data transmission link between the target USB host side and the target USB device side.
It should be noted that, the determination of whether the target USB host end has a data communication relationship with other USB device ends and the determination of whether the USB device end has a data communication relationship with other USB host ends may be performed simultaneously or sequentially, and the purpose is to detect whether the target USB host end has a data communication relationship with other USB device ends and whether the target USB device end has a data communication relationship with other USB host ends, and to issue a communication disconnection instruction in time, so that the target USB host end and the target USB device end are both in an idle state, and a unique data transmission link can be established between the target USB host end and the target USB device end. A USB host end and a USB device end establish a one-to-one data transmission link, which can improve the security of USB data signal sharing.
Further, the judgment condition that the target USB host end and other USB equipment ends have a data communication relation is that the target USB host end has a first occupation signal; and the judgment condition that the target USB equipment end and other USB host ends have the data communication relation is that the target USB equipment end has a second occupation signal.
It should be noted that, when there is a data transmission link between the USB host end and the USB device end, a lock signal, i.e. an occupied signal, is generated to indicate that there is a data transmission relationship between the USB host end and the USB device end, and the lock signal is occupied. Therefore, before establishing a data transmission link between the target USB host end and the target USB device end, it is necessary to first determine whether the target USB host end has a data transmission relationship with other USB device ends (i.e. there is a first occupation signal) and whether the target USB device end has a data transmission relationship with other USB host ends (i.e. there is a second occupation signal), and meanwhile, it is also possible to prompt that the current USB host end/USB device end is occupied through a program control interface of a server or a program control interface of a network side device.
In this embodiment, a data transmission link is established between the USB host end and the USB device end, so that the USB host end and the USB device end can perform data transmission based on the data transmission link, and because the USB host end is used to be electrically connected to the PC host, and the USB device end is used to be electrically connected to the USB device, when the USB device is far away from the PC host, the USB device at the far end can be connected to the USB device end, the USB data signal obtained from the USB device is converted into an ethernet frame data packet by the USB device end, and then the ethernet frame data packet is sent to the USB host, and then the USB host end converts the ethernet frame data packet into a USB data packet and sends the USB data packet to the PC host, so as to implement USB data signal sharing, thereby solving the technical problems that the USB host end cannot implement USB data signal sharing with the USB device at the far end and the flexibility is poor in the prior art.
