[0005] The above test method can only judge whether the universal serial interface is qualified based on whether the product under test can recognize the external storage device with the universal serial interface. The general-purpose interface is in good contact with the universal serial port of the external storage device, and the product under test can recognize the external storage device. However, when the general-purpose serial port of the product is in good contact but cannot transmit data, it cannot be detected. out, so the reliability of this test method is not high, wasting a lot of time and money

This invention is a kind of testing system and method for universal serial interface. By the testing program of the testing pending product, it recognizes the external storage that with the universal serial socket automatically. Then it transfers a sample data to these external storages in turn. The testing pending products read the data in these external storages in turn and compare with the original sample data, and judge whether the universal serial interface is eligible according to the comparing result. This testing system and method are not just judge whether the universal serial interface is eligible by recognizing external equipment, at the same time, it can transfer data between the testing pending product and the external equipment that with the universal serial socket.
Description
technical field [0001] The invention relates to a testing system and method of a universal serial interface, which is mainly used for testing whether the universal serial interface on an electronic product is qualified. Background technique [0002] Generally, electronic products (such as laptops) are provided with one or more general-purpose serial interfaces, and each general-purpose serial interface needs to be tested before the product leaves the factory to determine whether each general-purpose serial interface is qualified. [0003] The traditional test system uses external storage devices for testing, and each external storage device is connected with a universal serial socket, which can be matched with the general serial interface to be tested on the product to be tested, and each external storage device There is a display light on the equipment. In addition, each product to be tested is provided with a test program. [0004] During the test, insert the universal s...
