Problems solved by technology

[0006] The currently used USB port test method is to use a USB hard disk as a test tool, but this way of the prior art still has many defects, especially each USB port will be inserted into a USB hard disk for testing. One USB port needs multiple USB hard disks. If the machine under test is mass-produced, multiple USB hard disks are required for large-scale testing, which will greatly increase the test cost; in addition, when there is only one USB hard disk and the When multiple USB ports are tested, each USB port can only be tested separately, so the test efficiency is low

Embodiment Construction

[0059] Please refer to FIG. 1 , which shows a USB port connection test device 30 of the present invention. The USB port connection test device 30 is used to connect two upstream USB ports 10 and 20 located in an electronic device 40 having a USB port to connect two Data packets are transmitted between the upstream USB ports 10 and 20. The connection testing device 30 includes: a first USB port 31 for connecting to the first upstream USB port 10; a second USB port 32 for connecting to a second USB port 32 The upstream USB port 20; a data transmission line 33 for connecting the first USB port 31 and the second USB port 32; and a USB port adapter chip 34 on the data transmission line 33 for connecting the first upstream USB port 10 and the Data packet transmission is performed between the two upstream USB ports 20 .

[0060] USB port devices are divided into upstream USB port devices and downstream USB port devices. Data can only be transmitted when the downstream USB port device...

Abstract

This invention relates to a detection device and method of general serial main lines port connection, the first and second USB port separately connect the first and second upper USB port of the ready detection equipment. The two USB ports can transmit the data bag between the two upper USB ports by the data connection line of the two USB ports and the USB port transfer clips on the data transmit lines. It can transmit the measuring data bag between the two upper USB ports by the connection measuring device to detect whether the work of the two USB port is normal.

Description

technical field [0001] The invention relates to a USB port connection testing device and a method for testing a USB port using the connection testing device, in particular to a USB port that can detect two upstream USB ports at the same time, so that the efficiency is doubled in the test of the same amount of data. A port connection test device and a test method thereof. 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). As early as 1995, there were already PCs with USB ports, but due to the lack of software and hardware support, the USB ports of these PCs were left unused. After 1998, as Microsoft built a support module for the USB interface in the Windows 98 operating system, and with the increasing number of devices with USB ports, the USB interface technology gradually entered the practical stage. [0003] In recent years, with the pop...
