[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the present invention is described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0023] Figure 1 FIG. 1 is a flow chart of a USBIF authentication triggering method according to a first embodiment of the present invention. This embodiment is a USBIF authentication triggering method executed by a device under test. Figure 1 As shown, the USBIF authentication triggering method of this embodiment may include the following steps:

[0024] Step S11: Read the test information of the USB disk inserted into the USB interface of the device under test.

[0025] Specifically, in one embodiment, when the user inserts a USB flash drive into the USB interface of the device under test, the device under test will read the test information of the USB flash drive. For example, the test information may include but is not limited to the name information, manufacturer information, VID (vendor ID) value and PID (Product ID) value of the USB flash drive, etc.

[0026] Specifically, in one embodiment, the application software in the device under test needs to write the preset PID value for triggering the USB flash drive into the application software in advance. When the PID value of the USB flash drive is obtained and compared with the written preset PID value, if the PID value of the triggered USB flash drive is consistent with the preset PID value, the test mode corresponding to the PID value of the USB flash drive is triggered.

[0027] Specifically, in one implementation, the test information includes the name information, manufacturer information and PID value of the USB flash drive.

[0028] Step S12: Compare the pre-written trigger information with the test information.

[0029] Specifically, in one embodiment, the device under test compares the pre-written trigger information with the test information one by one to determine whether there is a PID value in the trigger information corresponding to the test information.

[0030] Specifically, in one implementation, the trigger information is a fixed preset PID value defined by the USBIF Association. Specifically, each test mode in the device under test corresponds to the preset PID value one by one as follows:

[0031]

[0032] Specifically, when the trigger information is consistent with the test information, step S13 is executed. When the trigger information is inconsistent with the test information, step S14 is executed.

[0033] Step S13: Automatically trigger the corresponding test mode according to the test information.

[0034] Specifically, in one embodiment, when the trigger information is consistent with the test information, for example, the PID value of the triggered USB flash drive is consistent with the preset PID value, the device under test automatically triggers the test mode corresponding to the PID value of the USB flash drive according to the test information, thereby enabling USBIF certification of the device under test without the need for dedicated test fixtures, saving testing costs.

[0035] Step S14: prompting information to change to a different USB flash drive.

[0036] Specifically, in one embodiment, when the trigger information is inconsistent with the test information, for example, when the trigger information does not contain a preset PID value corresponding to the PID value of the USB flash drive, the tested device generates a prompt message and displays the prompt message to remind the user to change to a different USB flash drive for USBIF certification testing to improve the user experience.

[0037] Please refer to Figure 2 , Figure 2 FIG. 2 is a flow chart of a USBIF authentication triggering method according to a second embodiment of the present invention. Figure 1 to Figure 2 As shown, the USBIF authentication triggering method provided in this embodiment further includes the following steps before the step of comparing the pre-written triggering information with the test information:

[0038] Step S21: receiving different trigger information written for test information of different USB flash drives.

[0039] Specifically, in one embodiment, the device under test receives setting information triggered by the user to set different trigger information for writing test information for different USB flash drives. For example, the application software in the device under test needs to write the preset PID value for triggering the USB flash drive into the application software in advance, so that it can be triggered by the USB flash drive. The number of USB flash drives can be, but is not limited to, 4. For example, when the test mode of the device under test increases, the number of USB flash drives also increases with the test mode of the device under test. Specifically, when 4 USB flash drives are inserted into the USB interface of the device under test one by one, the PID value of the USB flash drive read by the device under test corresponds to the PID value of the test fixture respectively, so that the USB interface in the device under test enters different test modes when different USB flash drives are inserted, thereby achieving the purpose of USBIF certification testing without the need for dedicated test fixtures, saving testing costs.

[0040] Step S22: Store the trigger information into a trigger information list.

[0041] Specifically, in one embodiment, the device under test stores all preset PID values ​​in the trigger information and the PID values ​​in each USB flash drive in correspondence with each other in the trigger information list.

[0042] Please refer to Figure 3 , Figure 3 FIG. 4 is a flow chart of a USBIF authentication triggering method according to a third embodiment of the present invention. Figures 1 to 3 As shown, the USBIF authentication trigger method provided in this embodiment, the step of receiving different trigger information written for test information of different USB flash drives specifically includes the following steps:

[0043] Step S31: multiple test modes in the tested device are matched one by one with the test information in multiple USB flash drives, and each piece of test information in the USB flash drive is matched with a test mode in the trigger information.

[0044] Specifically, in one embodiment, the device under test corresponds multiple test modes in the device under test to test information in multiple USB flash drives one by one, and the test information in each USB flash drive corresponds to a test mode in the trigger information. Specifically, each test mode corresponds to a preset PID value in the trigger information, and each preset PID value corresponds to a PID value of a USB flash drive, so that when the USB flash drive is inserted into the USB interface of the device under test, the device under test searches for the corresponding preset PID value according to the PID value of the test information in the USB flash drive, and then triggers the corresponding test mode according to the preset PID value, thereby achieving the purpose of USBIF certification testing without the need for a dedicated test fixture, saving testing costs.

[0045] Specifically, in one embodiment, the USBIF authentication trigger method provided in this embodiment does not need to determine the VID value. For example, the preset PID values ​​triggered by the functional test in the tested device are 0x0101, 0x0102, 0x0103, and 0x0104. Then, it is necessary to select four USB disks to correspond to them respectively. Specifically, the PID value 0x12A0 in the first USB disk corresponds to the preset PID value 0x0101. The PID value 0xA012 in the second USB disk corresponds to the preset PID value 0x0102, and so on.

[0046] Specifically, in one embodiment, after the device under test corresponds the PID value of the USB flash drive to the application software of the device under test, after the user inserts the corresponding USB flash drive into the USB interface of the device under test, the device under test detects the PID value of the USB flash drive. If the PID value is 0x12A0, the device under test determines the test fixture with a VID value of 0x1a0a and a preset PID value of 0x0101, and triggers the test mode TEST_SE0_NAK_PID corresponding to the preset PID value of 0x0101 for testing.

[0047] Specifically, the USBIF authentication trigger method provided in this embodiment reads the test information of the U disk inserted into the USB interface of the tested device, and compares the pre-written trigger information with the test information, so as to automatically trigger the corresponding test mode according to the test information when the trigger information is consistent with the test information, and prompt the user to replace a different U disk when the trigger information is inconsistent with the test information, thereby realizing USBIF authentication of the tested device without the need for dedicated test fixtures, saving test costs, and shortening the R&D cycle.

[0048] Figure 4 FIG. 1 is a structural block diagram of a device under test 100 according to a fourth embodiment of the present invention. Figure 4 As shown, the device under test 100 provided in this embodiment includes a memory 110 and a processor 120 .

[0049] Specifically, in one embodiment, the memory 110 is used to store executable program codes. The processor 120 is used to call the executable program codes in the memory 110 to implement the steps executed by the USBIF authentication trigger method, including: reading the test information of the USB disk inserted into the USB interface of the tested device; comparing the pre-written trigger information with the test information; when the trigger information is consistent with the test information, automatically triggering the corresponding test mode according to the test information; when the trigger information is inconsistent with the test information, prompting a prompt message to change a different USB disk.

[0050] Specifically, in one embodiment, the processor 120, before executing the step of comparing the pre-written trigger information with the test information, further executes the following steps: receiving different trigger information written for the test information of different USB flash drives; and storing the trigger information in a trigger information list.

[0051] Specifically, in one embodiment, the processor 120 executes the step of receiving different trigger information written for test information of different USB flash drives. The specific execution steps include: one-to-one correspondence between multiple test modes in the tested device and test information in multiple USB flash drives, and the test information in each USB flash drive corresponds to a test mode in the trigger information.

[0052] Specifically, in one embodiment, the test information includes the name information, manufacturer information and PID value of the USB flash drive.

[0053] Specifically, in one implementation, the trigger information is a fixed preset PID value defined by the USBIF Association. Specifically, each test mode in the device under test corresponds to the preset PID value one by one as follows:

[0054] #define TEST_SE0_NAK_PID 0x0101;

[0055]

[0056] Specifically, in one embodiment, the USBIF authentication trigger method provided in this embodiment does not need to determine the VID value. For example, the preset PID values ​​triggered by the functional test in the tested device are 0x0101, 0x0102, 0x0103, and 0x0104. Then, it is necessary to select four USB disks to correspond to them respectively. Specifically, the PID value 0x12A0 in the first USB disk corresponds to the preset PID value 0x0101. The PID value 0xA012 in the second USB disk corresponds to the preset PID value 0x0102, and so on.

[0057] Specifically, in one embodiment, after the device under test corresponds the PID value of the USB flash drive to the application software of the device under test, after the user inserts the corresponding USB flash drive into the USB interface of the device under test, the device under test detects the PID value of the USB flash drive. If the PID value is 0x12A0, the device under test determines the test fixture with a VID value of 0x1a0a and a preset PID value of 0x0101, and triggers the test mode TEST_SE0_NAK_PID corresponding to the preset PID value of 0x0101 for testing.

[0059] Specifically, the tested device provided in this embodiment reads the test information of the USB flash drive inserted into the USB interface of the tested device, and compares the pre-written trigger information with the test information, so as to automatically trigger the corresponding test mode according to the test information when the trigger information is consistent with the test information, and prompt the user to replace a different USB flash drive when the trigger information is inconsistent with the test information, thereby achieving USBIF certification of the tested device without the need for dedicated test fixtures, saving test costs, and shortening the R&D cycle.
