Description of the Invention: [Technical Field] [0001] The present invention relates to a test method and system, and more particularly to a method and system for testing a USB device of an electronic device. [Prior Art 3 [0002] With the rapid development of electronic technology, more and more peripheral devices of various electronic devices, such as computers, various peripheral devices such as keyboards, mice, printers, scanners, cameras, etc., need to be connected. To the host of the computer, various functions are implemented with 0, and the USB interface is widely used in order to allow such devices to be easily connected to electronic devices. [〇〇〇3] According to the USB specification, all USB devices have a vendor identification number (VID) and a product identification number (PID). The electronic device distinguishes between different vendor identification codes and product identification codes. The equipment, supplier identification and product identification code are two bytes long. The supplier identification code is negotiated by the supplier to the USB standard. 'The supplier identification code of each supplier is unique, the product identification code. It is up to the supplier to decide. Under normal circumstances, different products, different models of the same product, and different designs of the same model have different product identification codes to distinguish different devices of the same manufacturer. [0004] After the electronic device is assembled, it is necessary to detect whether various USB peripheral devices are connected to the electronic device intact. Generally, the weaving method is manually detected one by one, the test efficiency is low, and the test accuracy is not high.

A system for testing a USB device of an electronic device for testing whether an electronic device is connected to a corresponding USB device, the system comprising a test module, wherein the test module is provided with a storage unit, wherein the storage unit stores Each USB interface of the electronic device and a product identifier of a USB device that should be connected to each USB interface of the electronic device, the test module is respectively connected to each USB interface, and the product identification of the USB device connected to the corresponding USB interface is viewed. Whether the code is consistent with the storage unit, thereby determining whether the electronic device and the corresponding USB device are connected properly. Compared with the prior art, the method and system for testing a USB device of an electronic device of the present invention can effectively test whether the electronic device and the corresponding Usb device are properly connected. [Embodiment] Please refer to FIG. 1 and FIG. 2, a system for testing a USB device of an electronic device according to the present invention. 098144008 Form No. A0101 Page 4 / 12 pages 0982075338-0 [0012] 201122803 is used to test an electronic device 10 and corresponding Whether the USB device is properly connected or not, the electronic device 10 is provided with a plurality of USB interfaces, such as a first USB interface, a second USB interface, a third USB interface, etc., and the corresponding USB devices are respectively connected to the USB interfaces, for example, a first The USB device is connected to the first USB interface, a second USB device is connected to the second USB interface, a third USB device is connected to a third USB interface, etc., and the USB device connected to the USB interface can be a USB keyboard, USB sliding Mouse, USB camera, etc., these USB devices are respectively provided with corresponding supplier identification code and product identification code. [0013] The electronic device 10 is provided with a test module 12, and the test module 12 is connected to each USB interface of the electronic device 10. The test module 12 is provided with a storage unit 121, and the storage unit 121 stores [USB Port 1] : VID = 0x0000 is stored in each USB interface of the electronic device 1 and the USB device of the USB device that should be connected to each USB interface of the electronic device 1 , for example, the deposit unit 121 , PID = Oxffff; In the above example, VID represents the supplier identification code, and PID represents the product identification code - the above example indicates that the supplier USB identification code of the USB device connected to the first USB interface should be 0x0000, and the product identification code should be 〇 Xf fff. For different electronic devices, the configuration is different, and the USB devices connected thereto are different. The different types of electronic devices can be tested by modifying the storage unit 121 of the test module 12. If a USB device is not connected to an interface, the vendor identification code and the product identification code stored in the storage unit 121 are respectively 〇. [0014] Referring to FIG. 3, the test module 12 tests the electronic device 1 and the corresponding USB device. The method includes the following steps: [0015] Step 2 〇1 'The test module 12 is first connected to The first usb interface. 098144008 Form No. A0101 Page 5 / Total 12 Page 0992075338-0 201122803 [0017] [0019] [0022] [0022] Step 2〇2, view the connection to the USB interface Step 203: Comparing the vendor identifier and the product identifier with the vendor identifier of the same USB interface in the storage unit 121 and the product identifier to check whether the same is the same. If not, go to step 204; if they are the same, go to step 2 0 5. In step 204, the electronic device 10 and the corresponding USB device are not connected, and the test ends. Step 205: Check whether the USB interface is the last USB interface of the USB device. If it is the last USB interface, go to Step 2〇6; if it is not the last USB interface, go to step go?. In step 206, the electronic device 1 is connected to the corresponding device, and the test ends. Step 207' test module 12 is connected to the next interface and then returns to step 202.
