But, in explanation of the present invention, saved well-known part in the prior art, will not be described in detail at this.
Fig. 2 is the structure piecemeal synoptic diagram of USB device control device in the embodiments of the invention.
With reference to Fig. 2,220 of the USB port of USB device 120 and computing machine 210 are carried out USB by the USB connecting line and are connected, and computing machine 210 comprises the control part 211 of the power supply of controlling USB device 120; Monitor the data monitoring portion 212 that carries out data transmission with USB device that whether exists by above-mentioned USB port 220; Accept the keyboard input part 213 of the button input of the power supply of closing above-mentioned USB device 120 defined by the user.
At this moment, aforementioned calculation machine 210 includes the multiple functional block of object computer function, and the other parts in embodiments of the invention the necessary functional block here will not be described in detail.
At this moment, above-mentioned USB port 220 comprises the control signal according to the control part 211 of aforementioned calculation machine 210, can control the power switch portion 221 of electric power starting to USB device 120 power supply/close.
What carry out the supervision that whether there is data transmission in the above-mentioned certain hour is data monitoring portion 212, and accepting is keyboard input part 213 by the button input of user's powered-down.
To the button of the powered-down of above-mentioned keyboard input part 213 inputs, keyboard by computing machine or Genius mouse menu etc. are set in advance, and the user also can arbitrarily change.
At this moment, power to USB device 120 by the USB connecting line that is connected with USB port 220.
The data monitoring portion 212 of aforementioned calculation machine 210 to whether having data transmission to monitor, in set certain hour, in the absence of data transmission, gives control part 211 with this advisory by USB port 220.
The information that does not have data transmission in the certain hour of control part 211 according to data monitoring portion 212 notices, the control signal that is used for powered-down to power switch portion 221 outputs of USB port 220, control signal according to above-mentioned control part 211, power switch portion 221 closes the power pack that is connected on the USB connecting line, cuts off the power supply to USB device 120 power supplies.
Above-mentioned power switch portion 221 is connected the power pack in the coupling bar of USB connecting line and connected USB port 220, according to the operation of switch, can make power supply be able to On/Off, can use TR (Transistor transistor) or mechanical switch at this.
Under the cut state of power supply, the user wants to use corresponding USB device 120, and control part 211 makes USB device 120 power to power switch portion 221 output control signals, promptly can use corresponding USB device 120.
In addition, for not according to the transmission whether data are arranged by the power supply of user's intention control USB device 120, in the input media of keyboard that is similar to computing machine 210 or Genius mouse etc., the hot key or the interface menu of USB device power supply closed in additional setting, and under the situation with its input, keyboard input part 213 is notified to control part 211 according to the signal of input with it, so control part 211 can be controlled the power switch portion 221 to USB device 120 power supplies.
Fig. 3 is the operation flow sheet of USB device control method in the embodiments of the invention.
Step 301, with reference to Fig. 3, in computing machine 210, when being connected USB device 120 on the USB port 220 by the USB connecting line, computing machine 210 relies on plug-and-play feature, senses USB device 120, carries out spendable register.
The sensing of above-mentioned USB device 120 and login can realize by common well-known technology, will not be described in detail at this.
Simultaneously, under USB device 120 and the state that computing machine 210 is connected, in 210 in USB device 120 and computing machine, do not have within a certain period of time under the situation of data transmission, the data monitoring portion 212 of computing machine 210 makes the judgement that is not used in the certain hour, and judged result is notified to control part 211.
Step 302 judges whether USB device 120 is not used within a certain period of time.
Step 304, step 305, control part 211 are under the situation that USB device 120 is not used within a certain period of time, and the power switch portion 221 output control signals to USB port 220 make power-off.
Step 303, step 304, step 305, in addition, the situation that does not have data transmission in the non-certain hour, that is, under the fixed state of user, when the button that the input user has set in advance requires powered-down, keyboard input part 213 is accepted the button input, and notice control part 211, control part 211 control power switch portions 221 cut off the power supply to USB device 120 power supplies.
Step 306, step 307, simultaneously, there is not data transmission in the aforesaid certain hour, perhaps import the button of powered-down and the power supply of USB device 120 is under the closed condition by the user, when wanting to use USB device 120, control part 211 control power switch portions 221 make power supply begin power supply.
Step 308, step 309, along with the power supply of power supply, during USB device 120 operations, computing machine 210 sensings are connected and login with USB device, and USB device can be used.
According to said process, in the user is long-time, do not use under the situation of USB device 120, automatic or manual is power-off, when wanting to use, power-on again.So can prevent unnecessary waste electric power, also can solve USB device 120 because of the issuable problem of unnecessary power-on.
USB device control device and method in the embodiments of the invention with the state that keeps USB to connect, owing to can make the electric power starting of USB device/close, can be protected obsolete USB device so have, and prevent the characteristics of unnecessary power loss.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claims of the present invention variation, the modification of the above embodiment.
