Universal serial bus host controller rapid testing system and method thereof

Abstract

This invention discloses one common series bus host controller rapid test system and its method, which comprises the following steps: acquiring common series host controller right; establishing analogue series bus device; through virtual common series bus connecting multiple bus devices; activating designed real common bus device test program; receiving and catching user mode application program to send out data pack through common series bus; if it receives activation information, activating real common series bus device interface test program; if it receives test terminal information, terminating test program and giving back test result to user mode application program and ending real common series bus interface test.

Description

technical field [0001] The present invention relates to a USB host controller rapid test system and method thereof, in particular to a system and method for quickly testing a USB host controller by establishing an association between a virtual USB device and an actual USB interface to test a specific USB interface. Background technique [0002] Universal Serial Bus (Universal Serial Bus, English abbreviation: USB) is a new type of interface technology applied in the field of personal computer (PC). At present, when testing this kind of USB host controller chip, the combination of USB fixtures is basically used as a testing method. Usually, the USB fixture is connected to the computer first, then the driver of the USB fixture is loaded, and finally the application program in the user mode sends instructions to instruct the operating system to test, and then waits for the feedback from the operating system to calculate the USB data transmission according to the feedback inform...

AI Technical Summary

Problems solved by technology

Since the USB fixture is usually a single-chip microprocessor system, its processing speed is generally not comparable to that of a computer. Therefore, due to the mismatch between the processing speed of the single-chip microprocessor system and the computer, the entire test speed is reduced.

[0004] 2. Waste of human resources and increase testing costs

Testers are required to perform relevant operations to separately connect the USB fixture to the USB port of the computer during the test, which wastes valuable human resources, and because the need to use the USB fixture for testing increases the cost of testing and with the test requirements Constant changes and improvements always require continuous improvement of USB fixtures

[0005] 3. Increase the probability of error and reduce work efficiency

In addition, when it is found that the USB device is working abnormally, it is impossible to determine whether the port connection is abnormal or the USB device is working abnormally, so the test conclusion will be wrong. Therefore, it is necessary to check whether the USB device is working normally, which will inevitably lead to a decrease in work efficiency.
