Specific embodiment
Accompanying drawing with reference to the present invention carries out clear, complete description to the technical scheme in the embodiment of the present invention, shows
So, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based in the present invention
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained on the premise of not making creative work,
Broadly fall into the scope of protection of the invention.
Below in conjunction with accompanying drawing 1- accompanying drawing 2, the method for quick identification grafting usb equipment provided in an embodiment of the present invention is entered
Row is discussed in detail.
Refer to Fig. 1, Fig. 1 is a kind of flow process of an embodiment of method of quick identification grafting usb equipment of the present invention
Figure, the method specifically includes following steps s1-s3.
Step s1, pre-recorded every an article or item in a contract mark usb apparatus connecting is corresponding in an operating system when different usb port to be generated
Device path, the information of a device path and a usb port, the information of a target usb equipment；I.e. device path bag
Include information, the information of corresponding a target usb equipment of corresponding usb port.
In the embodiment of the present invention, described target usb equipment is the usb equipment needing detection, and same an article or item in a contract mark usb equipment is inserted
When being connected on different usb port, different device paths will be generated in an operating system, different an article or item in a contract mark usb apparatus connectings are same
During one usb port, also will generate different device paths in an operating system；Therefore, a device path of the present embodiment, be
Corresponding with the combination of a target usb equipment and a usb port.
Described different usb ports are the different usb ports of pc, and described operating system is the operating system of this pc, including
But it is not limited to windows operating system.Taking windows operating system as a example the present invention will be described for the present embodiment.
In windows operating system, a typical device path should have following form usb#vid_24ae＆pid_
2002#6&723e50&0&2#{a5dcbf10-6530-11d2-901f-00c04fb951ed}.Wherein: field " vid_24ae＆
Pid_2002 " represents the information of usb equipment, field " 6＆723e50＆0＆2 " and " { a5dcbf10-6530-11d2-901f-
00c04fb951ed } " represent the information of usb port.
The vid/pid of the same a usb equipment by being produced on production line must be the same, once so this usb
When apparatus connecting is on the same usb port of pc, the device path that windows operating system distributes to this usb equipment must be
The same.After device path is recorded, this device path can Reusability, that is, next time with a usb apparatus connecting to phase
During the usb port answered, device path need not be regenerated.
Step s2, according to the device path opening record of default time cycle property, is plugged on usb port to identify
Target usb equipment.
In the embodiment of the present invention, even if when target usb equipment is not also plugged on usb port, also can be when default
Between the function of call operation system open the device path of record once, this operation will force operating system active go to refresh current
It is plugged into the list of devices of usb port.Preferably, the described default time is 100～500 milliseconds.
Because the device path of record is reusable, it is plugged on by periodically opening device path and then identify
The target usb equipment of usb port, accelerates the recognition speed of the target usb equipment to grafting.

The device path of usb apparatus connecting corresponding generation in an operating system when different usb port, then adjusts every the default time
The device path opening record with the function of operating system once, thus shortening target usb to the usb port being plugged into pc
The recognition time of equipment, is conducive to improve the working performance that factory is detected to target usb equipment.
Method in order to a kind of quick identification grafting usb equipment of the present invention is explained in more detail, present invention also offers
A kind of flow chart of the second embodiment of method of quick identification grafting target usb equipment.The present embodiment is applied in windows
On the pc of operating system, this pc comprises multiple usb ports.Refer to Fig. 2, comprise the steps s21-s27.
Step s21, after initialization success, detects each usb port respectively.
Step s22, whether usb port is plugged with target usb equipment？If so, next step, otherwise, return to step are executed
s21.
Step s23, generates a corresponding device path in an operating system, and this device path comprises this usb port
Information, the information of this target usb equipment.Record this device path.
If this pc comprises 4 usb ports, same target usb equipment at most can correspond to 4 in the operating system of this pc
Device path.
In the present embodiment, described device path can be set as the pre-read file of operating system, fast oil (gas) filling device path
Opening speed.Windows under the system disk of windows operating system prefetch file be exactly to store pre-read file
Path, have many files with pf as extension name, i.e. pre-read file in prefetch file.
Step s24, arranges an intervalometer, this intervalometer is according to default time cycle property timing.Enter dormancy to wait.
Step s25, whether the intervalometer default time arrives？If so, execute next step, otherwise, re-execute this step.
Step s26, the function reading file in call operation system opens the device path of record.In windows operation
In system, that is, the createfile function in windows operating system is called to open the device path of record, control operation simultaneously
System refresh is currently plugged into the list of devices of usb port.
Step s27, identifies the target usb equipment being plugged on usb port by list of devices.
Terminate.
By above-described embodiment, pre-recorded every an article or item in a contract mark usb apparatus connecting when different usb port in an operating system
The corresponding device path generating, and device path record after can Reusability；Again every default time call operation system
The function of system opens the device path of record once, when shortening the identification to the target usb equipment of the usb port being plugged into pc
Between, be conducive to improve the working performance that factory is detected to target usb equipment.
