In a specific implementation, the first connection may include a connection of a power pin between the device under test interface 12 and the first device interface 13. The second connection may include a connection of a power pin between device under test interface 12 and second device interface 14.

Specifically, the data pins of the device interface to be tested 12, the first device interface 13, and the second device interface 14 may include pins used in the OTG test process and performing communication based on a switching protocol.

In particular, the switching protocol comprises the USB protocol.

In a specific implementation, the handover protocol may include at least one of a USB2.0 protocol, a USB3.2 Gen1 protocol, a USB3.2 Gen2 x 2 protocol, and a USB4.0 protocol.

In some embodiments, the handover protocol may further include at least two of a USB2.0 protocol, a USB3.2 Gen1 protocol, a USB3.2 Gen2 x 2 protocol, and a USB4.0 protocol. In this case, the control unit 15 is adapted to control the device interface under test 12 to make the connection of the corresponding data pins with the first device interface 13 based on the different switching protocols, respectively, when the switching state includes the master device state, and to control the device interface under test 12 to make the connection of the corresponding data pins with the second device interface 14 based on the different switching protocols, respectively, when the switching state includes the slave device state.

For example, when the switching state includes a master device state and the switching protocol includes the USB2.0 protocol and the USB3.2 Gen1 protocol, the control unit 15 is adapted to control the device under test interface 12 to make a connection with the first device interface 13 regarding a data pin of the USB2.0 protocol based on the USB2.0 protocol and to control the device under test interface 12 to make a connection with the first device interface 13 regarding a data pin of the USB3.2 Gen1 protocol based on the USB3.2 Gen1 protocol.

It will be appreciated that the switching protocol included in the switching instruction is related to the USB protocol supported by device under test interface 12. In particular, the switching protocol may include at least one of all USB protocols supported by device under test interface 12.

Based on the technical scheme, the test protocol of the to-be-tested OTG equipment 30 in the OTG test process can be flexibly switched based on the switching instruction, and the test equipment does not need to be manually plugged and pulled when the test protocol is switched, so that the automation of switching the test protocol in the OTG test process is realized.

In some embodiments, the control unit 15 is further adapted to determine whether the device interface 12 under test has established a connection with the first device interface 13 or with the second device interface 14 before controlling the first connection or the second connection, and to control the established connection between the device interface 12 under test and the first device interface 13 or the second device interface 14 to be disconnected in case the device interface 12 under test has established a connection with the first device interface 13 or with the second device interface 14.

In some embodiments, when the second connection is completed, the control unit 15 is further adapted to trigger the OTG device under test 30 to complete the self-switching of the device mode and trigger the second device 50 to identify the OTG device under test 30.

In a specific implementation, the device under test interface 12 further includes an OTG _ ID pin. The to-be-tested OTG device 30 may complete the self-switching of the device mode by detecting the state of the OTG _ ID pin.

When the device interface 12 to be tested and the first device interface 13 complete the first connection, the state of the OTG _ ID pin is grounded. In this case, the OTG device 30 under test is usually the master device by default.

When the device interface 12 to be tested and the second device interface 14 complete the second connection, the state of the OTG _ ID pin is floating. In this case, the OTG device 30 under test is typically the slave device by default.

In a specific implementation, the switching device 10 further comprises a first switch 16 and a second switch 17.

Specifically, the first switch 16 is connected between the device interface 12 to be tested and the first device interface 13, and is adapted to make a first connection between the device interface 12 to be tested and the first device interface 13 under the control of the control unit 15, or to break an established connection between the device interface 12 to be tested and the first device interface 13 under the control of the control unit 15.

In the specific implementation of step S62, the device interface 12 to be tested is controlled to perform the second connection with the second device interface 14 based on the switching instruction, which is suitable for enabling the OTG device 30 to be tested connected to the device interface 12 to be used as a slave device of the second device 50 connected to the second device interface 14 during the OTG test.

In particular implementations, the switch instruction may include a switch state. The switching state may in turn comprise a master device state or a slave device state.

In particular, the switching protocol comprises the USB protocol.

In some embodiments, the handover protocol may further include at least two of a USB2.0 protocol, a USB3.2 Gen1 protocol, a USB3.2 Gen2 x 2 protocol, and a USB4.0 protocol.

Before the second connection is made, the connection between the device interface 12 to be tested and the first device interface 13 or the second device interface 14 is disconnected.

Specifically, before controlling the first connection or the second connection, it may be determined whether the device interface 12 under test has established a connection with the first device interface 13 or the second device interface 14, and in a case that the device interface 12 under test has established a connection with the first device interface 13 or the second device interface 14, the established connection between the device interface 12 under test and the first device interface 13 or the second device interface 14 may be controlled to be disconnected. After the established connection is broken, the first connection or the second connection is made.
