In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic flowchart of a method for testing compatibility of a USB interface according to the present application, where the method is applied to a processor in a server, the server further includes a USB interface to be tested and a splitter, an uplink interface of the splitter is connected to the USB interface to be tested, a plurality of downlink interfaces of the splitter are respectively connected to USB interfaces of a plurality of devices, and a version of the USB interface is not higher than a version of the USB interface to be tested;
the method for testing the compatibility of the USB interface comprises the following steps:
s11: calling information of each device connected with the deconcentrator from a preset storage area, wherein the information comprises an identifier of the device and a transmission rate of a baseband signal of the device, and the information of each device stored in the preset storage area is information obtained and stored by an operating system of a server through a USB interface to be tested when each device is connected with the server through the deconcentrator;
s12: determining a type of the device based on the identity of the device;
s13: and judging whether the USB interface to be tested is compatible with the type equipment or not based on the transmission rate and the type of the baseband signal.
In the prior art, a USB technology is used as an external bus standard to standardize connection and communication between a computer and external equipment, the USB has the advantages of high transmission speed, convenience in use, hot plugging support, flexibility in connection, independent power supply and the like, and can be connected with various peripheral devices such as a keyboard, a mouse and a large-capacity storage device, and the electronic equipment mainly performs data interaction through a network and a USB interface. Since the launch of USB, USB has successfully replaced serial and parallel ports, becoming one of the standard expansion interfaces and the requisite interfaces for a large number of computers and intelligent devices. With the continuous breakthrough and improvement of technologies and standards, the bus standard of the USB is continuously updated and changed, for example, from USB2.0 supporting 480Mbps high rate to USB3.0 supporting 5Gbps ultrahigh rate, and meanwhile, the USB technology has a policy of compatibility in the first place, that is, USB3.0 is compatible with USB2.0 in the downward direction, and the improvement of the standard is essentially the improvement of signal transmission. In the server and PC (Personal Computer) industry, the USB3.0 interface is widely used, and both achieve downward compatibility, which can ensure the compatibility of peripherals of different clients to the maximum extent.
In the prior art, when testing the compatibility of a USB3.0 interface to be tested, a USB2.0 USB flash disk needs to be manually inserted, and whether the compatibility is realized is judged according to the read-write speed of the USB flash disk; then, manually replacing the USB3.0 USB flash disk, and judging whether the USB flash disk is compatible or not according to the reading and writing speed of the USB flash disk; the sequence of the two USB flash disks can be changed, and the process of replacing the USB flash disks consumes manpower. And the read-write speed of the USB flash disk can be greatly reduced under the influence of the material and the service life of the USB flash disk, so that the condition that the USB3.0 interface to be tested can be compatible with the USB flash disk but is wrongly judged to be incompatible occurs, and the accuracy of judging the compatibility of the USB3.0 interface to be tested is reduced. In addition, the service life of the USB flash disk can be shortened by reading and writing the USB flash disk.

Specifically, when each device is connected with the server through the splitter, the operating system of the server automatically obtains and stores information about each device through the detection of the USB interface to be tested, for example, the operating system detects the identifier of each device and also detects the actual transmission rate of the baseband signal of each device, then generates a folder named as a device number based on the identifier of the device and the actual transmission rate of the baseband signal of the device, and then generates a folder named as a bus number based on each folder named as a device number, and the same USB interface to be tested corresponds to one bus number, the application calls the information of each device by using the characteristics of the complaints, realizes the automatic calling of the information of the device and the transmission rate of the baseband signal, and then can judge the type and compatibility of the device, and can improve the test coverage rate and the automation degree of the USB interface to be tested in the server and PC industries, the efficiency in the aspect of function detection and the accuracy of test are improved.
It should be noted that, the identifier of each device is different, so that the type of the device can be determined by the identifier of the device, and the type may include USB2.0 and USB 3.0. Specifically, in the determining process, for example, when the identifier of the device of USB2.0 stored in advance includes the acquired identifier of the device, it is determined that the type of the device is USB 2.0.
Meanwhile, the judgment result can be finally displayed by printing. In addition, when the standard of USB4.0 is implemented, the compatibility determination may also be made with reference to the present application.
In summary, the present application provides a method for testing compatibility of a USB interface, in the scheme, information of each device connected to a splitter is retrieved from a preset storage area, where the information includes an identifier of the device and a transmission rate of a baseband signal of the device; determining a type of the device based on the identity of the device; and judging whether the USB interface to be tested is compatible with the type equipment or not based on the transmission rate and the type of the baseband signal. According to the scheme, the plurality of devices are connected with the USB interface to be tested through the deconcentrator, so that a tester does not need to manually replace different devices in the testing process, and the manpower is saved; after the type of the equipment is identified, whether the equipment is compatible or not is judged directly according to the transmission rate of the baseband signal of the equipment, the transmission rate of the baseband signal is not influenced by the material and the service life of the equipment, and the accuracy of judging the compatibility of the USB interface to be tested is improved. In addition, the equipment does not need to be read and written, and the service life of the equipment is not shortened.

When the type of the device is judged to be USB2.0, if the transmission rate of the obtained baseband signal is 480Mbps, the device with the compatible type of the USB interface to be tested being USB2.0 is judged, and otherwise, the device is judged to be incompatible.
In summary, whether the USB interface to be tested is compatible with the device is determined according to the transmission rate of the baseband signal, and since the transmission rate of the baseband signal is not affected by the material and the service life of the device, the compatibility of the USB interface to be tested can be determined more accurately.
