The invention relates to a method for testing by using a USB port connection testing device, in particular to a testing method capable of simultaneously detecting two upstream USB ports, so that the efficiency of the USB port connection test can be doubled in the test of the same amount of data Device and its test method.

Background technique

Universal Serial Bus (Universal Serial Bus, English abbreviation: USB) is a new 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, coupled with the increasing number of devices with USB ports, the USB interface technology gradually entered the practical stage.

In recent years, with the popularization of a large number of personal computers supporting USB ports, it is the general trend that USB ports gradually become the standard ports of PCs. On the host side, almost 100% of the latest PCs support USB interfaces; and on the peripheral side, electronic devices using USB interfaces are also increasing day by day, such as digital cameras, scanners, joysticks, tapes and floppy drives, image processing equipment, printers, Keyboard, mouse, etc.

The early use of the USB interface to transmit data was based on the USB1.0/1.1 standard. The USB port 1.0/1.1 standard can transfer up to 1.5Mbps for low-speed devices; for full-speed devices, the transfer rate can reach up to 12Mbps. Since the transfer rate of the USB1.0/1.1 standard is relatively low, it will take a lot of time to transfer a large amount of data. So seven manufacturers, COMPAQ, Hewlett Packard, Intel, Lucent, Microsoft, NEC and PHILIPS, jointly formulated the USB2.0 interface standard. The USB2.0 interface standard increases the data transmission rate between devices to 480Mbps, which is about 40 times faster than the USB1.1 standard. The biggest benefit of the increase in the transmission rate for users is that they can use more efficient external devices, and Interface devices with multiple rates can be connected to the line using the USB2.0 interface standard, and there is no need to worry about bottleneck effects during data transmission. The USB2.0 standard can support a data transfer rate of up to 480Mbps for high-speed devices. It is mainly suitable for high-performance external devices such as high-definition cameras, high-resolution scanners, and large-capacity portable memory. Moreover, the USB2.0 interface standard is also backward compatible with the old USB1.0/1.1 software and devices, so users can avoid problems caused by compatibility.

The USB interface is supported in the Windows operating system, and the WINDOWS XP operating system can fully support USB2.0 devices. It unifies the specifications of the peripheral communication ports of personal computers. The USB interface supports plug-and-play and hot plug (hot plug), has strong scalability, and provides a low-cost standard data transmission form for peripheral devices. Whether it is a simple input device such as a keyboard, mouse, or joystick, or an advanced external device such as a printer, a scanner, a storage device, or a camera, the USB interface can be used, and almost all peripheral devices are included. There are often multiple upstream USB ports on a PC, and several downstream USB devices can be connected at the same time.

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.
