New description: [New technical field] [0001] The utility model relates to an electrical testing device, in particular to a USB testing device. [Prior Art] [0002] At present, engineers generally use a Universal Serial Bus (USB) loopback jig to test whether the USB port of the machine is normal. The USB loopback fixture typically has a first male interface, a second male interface, and a control wafer. When testing the USB port, the first male interface and the second male interface of the USB ring checker are respectively connected to the first USB port to be tested and the second USB port to be tested, and the machine sends the same. The data is outputted by the first USB device to be tested and the first male interface, and the data is converted and transmitted by the control chip, and returned to the machine via the second male interface and the second USB to be tested. And detecting whether the information sent by the machine and the received data are consistent; then the machine sends the data again through the second USB interface to be tested and the second male interface output, and the data is converted and transmitted by the control chip. After returning to the machine via the first male interface and the first USB to be tested, the information sent by the inspection machine and the received data are consistent. If the data sent by the machine and the received data are always consistent, it is determined that the two USB ports under test are normal. [0003] In the actual test process, sometimes the data inconsistency sent and received is not caused by the machine failure, but because some files included in the software of the machine need to be upgraded or the test software needs to be updated. In this case, you usually need to use the mobile storage device to import the relevant upgrade patches or update files, and then test again to get accurate test results. However, when the number of USB ports on the table of the form number A0101/4/14 is small, there may be no USB other than the USB port under test for the storage upgrade or update of the mobile storage. Set up a borrower. At this time, it is often necessary to unplug the interface of the (4) loopback tool from the USB port of the machine to insert the mobile storage device, import the upgrade patch or update the file, then unplug the mobile storage device, and re-plug the USB ring to test the tool. If it is frequently plugged and unplugged, it will cause more damage to the USB of the machine.
