Problems solved by technology

However, such a test cannot detect the data transmission error rate of the connection interface, nor can it perform a transmission stress test, that is to say, such a test is not complete
[0005] To sum up, it can be seen that there has been a problem that the connection interface cannot be tested completely and efficiently in the prior art for a long time, so it is necessary to propose improved technical means to solve this problem

Abstract

The invention discloses a hot swapping / hot plugging device and method for conducting automatic switching of protocols to establish and test a data channel. The technical effect that a connection interface of a host computer to be tested is automatically, completely and efficiently tested can be achieved due to the technical means that after the hot swapping / hot plugging device uses a first protocol to establish the data channel with the host computer to be tested, test data transmitted by the host computer to be tested are received, the connection interface of the host computer to be tested is tested according to the transmitted test data, and after the test is accomplished, the hot swapping / hot plugging device is restarted so that the hot swapping / hot plugging device can continue to use a second protocol to establish the data channel with the host computer to be tested, and the connection interface of the host computer to be tested can be tested according to test data which are transmitted again by the host computer to be tested.

Description

technical field [0001] The present invention relates to a hot-swapping device and its use method, in particular to a hot-swapping device and method for automatically switching protocols to establish and test data channels. Background technique [0002] At present, a specific connection interface in the host may support multiple protocols of different specifications. For example, the USB connection interfaces of most computers currently support the USB2.0 or USB3.0 protocol, so that the USB device connected to the computer can use The protocol of USB2.0 or USB3.0 establishes a data channel with the computer. However, for computer manufacturers, after the computer is manufactured, if it is necessary to test connection interfaces supporting different protocols, it is necessary to use a device supporting different protocols to connect to the computer. In this way, the testing process cannot be performed automatically. [0003] In order to be able to automatically complete the t...
