It should be noted that, the input end of the USB line may be connected to a plurality of USB devices, and one of the USB devices is selected for performing abnormality detection. In addition, when the number of USB ports on the terminal equipment is insufficient, the terminal equipment can be connected with the output end of the USB line through a USB hub (hub); the USB hub may be integrated in the terminal device, or may be externally connected to the terminal device.
Optionally, the USB line may be a commercial display touch (touch) working circuit, the USB output line may be a touch (touch) line, referring to fig. 2, fig. 2 is a schematic diagram of the USB line, and the touch line may refer to a touch line such as an open pluggable specification (open pluggable specification, OPS) touch line, a high-definition multimedia interface (high definition multimedia interface, HDMI) touch line, a display interface (DP) touch line, and a video graphics array (video graphics array, VGA) touch line. The USB hub is shown for connecting a USB device to a USB switch (switch) that is used to control the switching of the touch line.

Optionally, before sending the line switching instruction to the motherboard, the method further includes: and receiving connection success prompt information from the main board, wherein the connection success prompt information is used for indicating that the USB equipment is successfully connected.
The main board can detect whether the USB equipment is successfully connected with the USB circuit, and after the USB equipment is successfully connected with the USB circuit, the main board can send a connection success prompt message to the terminal equipment through the communication circuit. The communication line is a line for communicating with the terminal device through the motherboard other than the USB line, and by way of example and not limitation, the motherboard and the terminal device may communicate through a connection data line.
Alternatively, the line switching instruction may be sent to the main board through a communication line. The line switching instruction may be used to instruct the motherboard to switch to a target USB output line, where the target USB output line may be specified by a user, or may be determined based on a set line detection order. For example, there are A, B, C three USB output lines, the set line detection order is to detect from a to C in order, and after the line detection is completed, the target USB output line can be determined to be C based on the set line detection order.
Step 102, obtaining device information of the USB device through the USB line.
Alternatively, there may be a case where information is lost when the device information is acquired, and in order to ensure that the device information can be acquired, the device information of the USB device may be acquired multiple times.
Alternatively, in order to ensure that the motherboard has received the line switching instruction or has executed the line switching instruction, after receiving the response information sent by the motherboard in response to the line switching instruction, the device information of the USB device may be obtained through the USB line. The response information indicates that the motherboard has received the line switching instruction or has executed the line switching instruction.

Embodiment two:
referring to fig. 3, fig. 3 shows a schematic flow of an abnormality detection method for a USB circuit of a motherboard provided in the present application.
Step 301, a line switching instruction is sent to the motherboard.
Step 302, obtaining device information of the USB device through the USB line.
The relevant content in steps 301-302 may be referred to the relevant description in steps 101-102, and will not be described here again.
Step 303, obtaining the port identifier of the output end of the transmission device information.
When the main board is in line switching, the line switching failure can be caused due to the damage of the USB hub or the USB switch, namely the line switching failure is remained on the original USB output line, at this time, under the condition that the original USB output line is normal, the equipment information can still be obtained through the original USB output line, which can lead to inaccurate test results and erroneous test judgment.
Therefore, in order to avoid the above situation, the present application also acquires the port identifier of the output end of the transmission device information.
The port identification may be pre-set. Alternatively, the port identification may be determined according to the group number (group) and the identification number (id) of the port, and the port identification BS may be calculated according to the formula bs=id+4 (group-1), by way of example and not limitation; the ports can be numbered sequentially according to the set sequence to obtain the port identification.
As an example, assuming that there are four outputs, the groups and ids corresponding to the four outputs may be (group=0, id=1), (group=0, id=2), (group=0, id=3), (group=0, id=4), respectively. Assuming that eight output terminals are provided, the groups and ids corresponding to the eight output terminals may be (group=0, id=1), (group=0, id=2), (group=0, id=3), (group=0, id=4), (group=1, id=1), (group=1, id=2), (group=1, id=3), (group=1, id=4), respectively.
Step 304, determining exception information based on the device information and the port identification.
The USB output line for transmitting the equipment information can be determined by combining the port identification, so that whether the line is successfully switched or not can be determined according to the port identification when the equipment information is acquired, and further, the abnormal information can be determined.
Optionally, determining the anomaly information based on the device information and the port identification includes: if the equipment information is preset equipment information and the port identifier is the identifier of the output end corresponding to the switched USB output line, obtaining abnormal information indicating that the switched USB output line is normal; if the equipment information is preset equipment information and the port identification is not the identification of the output end corresponding to the switched USB output line, obtaining abnormal information representing abnormal switching of the USB output line.
By way of example and not limitation, there are A, B, C three USB output lines, and the line switch instruction instructs to switch line B to C. If the acquired equipment information is the same as the preset equipment information and the port identifier is the port identifier corresponding to the port identifier C, abnormal information indicating that the switched USB output line is normal can be obtained. If the acquired equipment information is the same as the preset equipment information, but the port identifier is the port identifier corresponding to the port identifier B, the abnormal information indicating that the USB output line C is abnormal in switching can be obtained.
Alternatively, if the device information is not acquired, it cannot be determined whether the line is successfully switched, and the abnormality information indicating that the USB line is abnormal may be obtained.
According to the method and the device, based on the equipment information and the port identification, the abnormal information of the switched USB output line is determined, the situation that test misjudgment occurs under the condition that the line is not switched successfully can be avoided, and the situation that the USB output line is switched abnormally can be detected.
