Description

Utilize USB (universal serial bus) port to connect the method that proving installation is tested
Technical field
The present invention relates to a kind of USB port of utilizing and connect the method that proving installation is tested, particularly relate to the method for testing that can detect two upstream USB port simultaneously, therefore in the test of same data volume, the USB port that efficient is doubled connects proving installation and method of testing thereof.
Background technology
USB (universal serial bus) (Universal Serial Bus, English abbreviation: USB) be a kind of new interface technology that is applied in personal computer (PC) field.As far back as nineteen ninety-five, just have PC to have USB interface, but owing to lack the support of software and computer hardware, the USB interface of these PCs is all left unused and is not used.After 1998, along with Microsoft's built-in support module to USB interface in Windows 98 operating systems, add day by day increasing of the equipment that has USB port, the USB interface technology has just progressively been come into the practical stage.
These several years, along with popularizing of the personal computer of a large amount of support USB port, the standard interface that USB interface progressively becomes PC was trend of the times.In host side, the PC of up-to-date release almost 100% is supported USB interface; And at the peripheral hardware end, the electronic equipment of use USB interface also grows with each passing day, for example digital camera, scanner, rocking bar, tape and floppy drive, image processing equipment, printer, keyboard, mouse or the like.
Utilize its standard of USB interface transmission data to be the USB1.0/1.1 standard in early days.USB port 1.0/1.1 standard can reach 1.5Mbps for the low-speed device transfer rate; For full speed equipment, the transfer rate maximum can reach 12Mbps.Because USB1.0/1.1 standard transmission speed ratio is lower, if need transferring large number of data then to expend time in more.So uniting, this 7 tame manufacturer of COMPAQ, Hewlett Packard, Intel, Lucent, Microsoft, NEC and PHILIPS formulated the USB2.0 interface standard.The USB2.0 interface standard has been increased to 480Mbps with data transfer between devices speed, than USB1.1 standard fast about 40 times, the raising of transfer rate means exactly that for user's largest benefit the user can use external unit more efficiently, and the interfacing equipment with multiple speed can be connected on the circuit that uses the USB2.0 interface standard, and ink-bottle effect takes place when need not the concern of data transmission.The USB2.0 standard can be supported data transmission rate up to 480Mbps for high-speed equipment, and it mainly is applicable to the high performance external equipment of camera, high-resolution scanner and the jumbo portable internal memory and so on of high image quality.And, the USB2.0 interface standard is also backward compatible old USB1.0/1.1 software and equipment, therefore, the problem of user with regard to having avoided causing owing to compatible.
Support USB interface in Windows operating system, WINDOWS XP operating system can be supported USB2.0 equipment fully.It is with the unified specification of specifying of peripheral communications port of personal computer, and USB interface is supported plug and play and hot plug (hot plug), has powerful extensibility, for peripherals provides standard data delivery form cheaply.No matter be the simple input equipment of keyboard, mouse, recreation rocking bar and so on for example, still the senior external unit as printer, scanner, storage facilities, camera and so on can adopt USB interface, has almost comprised all peripherals.On a PC, often have a plurality of upstreams USB port, can connect several downstreams USB device simultaneously.
Present employed USB port method of testing is to use the USB hard disk as testing tool, yet this way of prior art still has many defectives, particularly each USB port will be inserted a USB hard disk and tests, if tested machine has a plurality of USB port just to need polylith USB hard disk, if tested machine is produced in batches, then need polylith USB hard disk to test on a large scale, so must increase testing cost greatly; In addition, in the time of will testing a plurality of USB port in that a USB hard disk is only arranged, can only respectively each USB port be tested, thereby testing efficiency is low.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of USB port of utilizing to connect the method that proving installation is tested, performance in order to the USB port of test electronic, can save cost greatly, can detect two upstream USB port simultaneously, therefore in the test of same data volume, the efficient of using this USB port connection proving installation to test can double.
The invention provides a kind of USB (universal serial bus) port of utilizing and connect the method that proving installation is tested, utilizing this USB (universal serial bus) port to connect proving installation tests first upstream USB (universal serial bus) port on the electronic installation and one second upstream USB (universal serial bus) port, this USB (universal serial bus) port connects proving installation and includes one first USB (universal serial bus) port, one second USB (universal serial bus) port, one data line and that connects above-mentioned first USB (universal serial bus) port and second USB (universal serial bus) port is positioned at the USB (universal serial bus) port connect chip on this data line, its characteristics are that this is surveyed the method for establishing and comprises following steps:
