Embodiment
Below in conjunction with accompanying drawing of the present invention, technical scheme in the embodiment of the present invention is carried out to clear, complete description, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belong to the scope of protection of the invention.
Below in conjunction with accompanying drawing 1-accompanying drawing 2, the method for the quick identification grafting USB device that the embodiment of the present invention is provided describes in detail.
Refer to Fig. 1, Fig. 1 is the process flow diagram of an embodiment of the method for a kind of quick identification grafting USB device of the present invention, and the method specifically comprises the steps S1-S3.
Step S1, the device path that when pre-recorded every an article or item in a contract mark USB device is plugged on different USB port, correspondence generates in operating system, the information of a device path and a USB port, the information of a target USB device; Be the information of the device path information that includes corresponding USB port, corresponding a target USB device.
In the embodiment of the present invention, described target USB device is for needing the USB device detected, when same an article or item in a contract mark USB device is plugged on different USB port, to generate different device paths in operating system, when different an article or item in a contract mark USB device are plugged on same USB port, in operating system, also will generate different device paths; Therefore, a device path of the present embodiment, be corresponding with the combination of a target USB device and a USB port.
The different USB port that described different USB port is PC, the operating system that described operating system is this PC, include but not limited to Windows operating system.The present embodiment be take Windows operating system, and as example, the present invention will be described.
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 " represent the information of USB device, field " 6& 723e50& 0& 2 " and " { a5dcbf10-6530-11d2-901f-00c04fb951ed} " represent the information of USB port.
Because the VID/PID of the same a USB device of producing on production line must be the same, once this USB device, be plugged on the same USB port of PC like this, the device path that Windows operating system is distributed to this USB device must be the same.After device path is recorded, but this device path Reusability, while being plugged into corresponding USB port with a USB device, without regenerating device path next time.
Step S2, according to the device path of opening record of default time cycle property, to identify the target USB device that is plugged on USB port.
In the embodiment of the present invention, even when the target USB device also is not plugged on USB port, once, this operation will force operating system initiatively to remove to refresh the current list of devices that is plugged into USB port to the device path that also can open record every the function of default time call operation system.Preferably, the described default time is 100～500 milliseconds.
Because the device path of record is reusable, by periodically opening device path and then identifying the target USB device that is plugged on USB port, accelerated the recognition speed of the target USB device to pegging graft.
The method of the quick identification grafting USB device by the above embodiment of the present invention, by pre-recorded, the device path that when every an article or item in a contract mark USB device is plugged on different USB port, correspondence generates in operating system, then the device path of opening record every the function of default time call operation system once, thereby shortened the recognition time of the target USB device of the USB port to being plugged into PC, be conducive to improve the operating efficiency that factory is detected the target USB device.
For the more detailed method of explaining a kind of quick identification grafting USB device of the present invention, the present invention also provides a kind of process flow diagram of the second embodiment of method of quick identification grafting target USB device.The present embodiment is applied on the PC of Windows operating system, and this PC comprises a plurality of USB port.Refer to Fig. 2, comprise the steps S21-S27.
Step S21, after the initialization success, detect respectively each USB port.
Step S22, is USB port plugged with the target USB device? if, carry out next step, otherwise, step S21 returned to.
Step S23 generates a corresponding device path, the information of the information that this device path comprises this USB port, this target USB device in operating system.Record this device path.
If this PC comprises 4 USB port, same target USB device at most can corresponding 4 device paths in the operating system of this PC.
In the present embodiment, described device path can be set as to the pre-file reading of operating system, the opening speed in fast oil (gas) filling device path.Windows under the system disk of Windows operating system the Prefetch file be exactly the path of the pre-file reading of storage, the file that many PF of take are extension name is arranged in the Prefetch file, i.e. pre-file reading.
Step S24, arrange a timer, and this timer is according to default time cycle property timing.Entering dormancy waits for.
Step S25, does the default time of timer arrive? if, carry out next step, otherwise, re-execute this step.
Step S26, in the call operation system, the function of file reading is opened the device path of record.In Windows operating system, call the device path that createfile function in Windows operating system is opened record, simultaneously the current list of devices that is plugged into USB port of control operation system refresh.
Step S27, identify the target USB device that is plugged on USB port by list of devices.
Finish.
By above-described embodiment, when pre-recorded every an article or item in a contract mark USB device is plugged on different USB port in operating system the corresponding device path generated, but and device path record after Reusability; The device path of opening record every the function of default time call operation system again once, has shortened the recognition time of the target USB device of the USB port to being plugged into PC, has been conducive to improve the operating efficiency that factory is detected the target USB device.
Below the embodiment of the device that provides for the embodiment of the present invention.The embodiment of device and above-mentioned embodiment of the method belong to same design, and the detail content of detailed description not in the embodiment of device, can be with reference to said method embodiment.
Below in conjunction with accompanying drawing 3, the quick identification grafting USB device that the embodiment of the present invention is provided device describe in detail.It should be noted that, following apparatus can be applied to carry out said method.
Refer to Fig. 3, described device comprises: module 320 is opened in path logging modle 310, path.
Preferably, wherein, described path logging modle 310, specifically for: at initial phase, detect respectively each USB port and whether be plugged with the target USB device; If USB port is plugged with the target USB device, generate a corresponding device path, the information of the information that described device path comprises this USB port, this target USB device in operating system; The device path that record generates respectively.Preferably, the logging modle of path described in the present embodiment 310 is set as described device path the pre-file reading of operating system.Specifically described with reference to above-described embodiment, do not repeat.
Wherein.The described default time is 100～500 milliseconds.
