Nowadays, smartphone is both a data storage and an application player. Sometimes we just need to connect the phone to the computer to upload or download something. At this time, I wonder if you have encountered this situation: that is, the phone USB can not connect to the computer, the connection to the computer does not respond. What should we do at this point?
First, find the reason why there is no response?
A, the phone, data cable interface failure

Second, the phone motherboard failure
Solution: Find the aftermarket!
Third, the software failure

Five, the phone USB port power supply is insufficient.
Cell phone USB port power supply is insufficient to charge the battery before connecting to the computer, but this is too inconvenient. Let the phone in the moment of connection to the computer USB interface power supply is not less than the phone's power consumption, so that at this moment should be "USB interface power supply is sufficient". How to do it? Close all processes, turn off the phone screen, then connect to the computer, in short, reduce the power consumption of the phone on the line. I do not guarantee that everyone will be successful when using this method, but at least it can bring help to those who have problems in this area.
Six, the phone connected to the computer only shows charging, can not do anything else with
Turn on the smartphone USB debugging mode. If the phone is an Android phone, please enter the phone settings - applications - development, check the USB debugging mode can be checked inside.
Nowadays, the majority of the use of Android smartphones, by default, Android phones connected to the computer is required to open the USB debugging mode, not debugging, you can only charge the phone. Like some commonly used 91 cell phone assistant or pea pod can not identify the phone. Many times it is due to not open the USB debugging in the phone settings, resulting in the computer can not find the phone storage disk, pea pod and other computer software can not connect to the phone, so it becomes the phone connected to the computer intelligent display charging.
Seven, driver problems lead to cell phone usb can not connect to the computer
Check the "USB connection type" settings, manually install the driver, click on the transmission page to download.

Computer interface problems
Cause of the problem: the problem is common in too old computers, or computer front interface power supply is insufficient!
Solution: Some desktop computers have chassis front and chassis back USB interface, and chassis front USB interface internal need to be connected to the motherboard, if the installation of the front of the chassis without the USB cable into the motherboard, the front of the computer chassis USB interface is not available, so if you encounter this situation you can try to connect the cable to the desktop computer chassis back USB interface try (rear USB interface directly from the motherboard, there is generally no problem).
In addition to check whether the problem is the USB interface, you can also take a U disk or USB mouse to test whether the interface is useful, etc.. There is also a possibility that the USB interface is blocked in the BIOS settings, usually Internet cafes will use this way, if the use of cell phone data cable in Internet cafes connected to the computer does not respond to most of this situation, you can consult the Internet cafe attendant to understand.
Cell phone interface problems
The reason for the problem: the quality of the phone, or too hard to dial plug, rust will probably appear this problem!
Solution: To check whether the USB interface is useful, the most direct way is to connect the USB cable and the phone to see if the phone is charging tips, if the phone cable connected to the computer, only shows in the charging, and can not operate on the computer, the first indication that the computer USB interface is not a problem. If the phone cable is connected to the computer, the phone does not have any anyway, then either the phone cable is bad (this situation is generally less, unless the phone cable into the water or fall bad, etc.), or the computer USB interface is not available.
Computer operating system problems or the system comes with the driver caused

2. If the failure persists, please use the system comes with the system restore, restore to the time you do not have this failure to repair (if the normal mode recovery failed, please boot up and press F8 to enter the safe mode to use the system restore).
3. If the failure persists, use the system disk repair, open the command prompt and enter SFC/SCANNOW enter (there is a space between SFC and /), insert the original system disk repair system, the system will automatically compare the repair.
4. If the failure persists, set the optical drive as the first boot device in the BIOS insert the system installation disk and press the R key to select "Repair Installation".

Of course, there are some extremely small possibilities, such as cell phone problems, cell phone USB data interface damage, etc., but this situation generally rarely occurs, in general, cell phone data cable to connect to the computer does not respond to the failure of the causes are not many, the main thing is to pay attention to the troubleshooting, the same try.
