Hello everyone, Lin Fei to answer the above questions, usb connection to the computer did not respond, usb connection to the computer did not respond to many people do not know, now let's take a look at it!

What if there is no response when the mobile data cable is connected to the computer?

Some friends do not respond when they connect to the computer with a data cable. What's going on? When there is no response when the data cable is connected to the computer, take a look at what kind of mobile phone you are using. In general, if you want to connect a non-smartphone to your computer, you need to install the PC package driver on your computer before you can use it. But if it's a smartphone, we won't talk about it here. In addition, Android phones and iPhone phones are now the most common, and mobile drivers need to be installed for the first time. The following is a detailed description:

The most likely reason why the data line of a mobile phone connected to a computer is not responding is:

1.USB interface is not available.

The most direct way to check the usefulness of the USB port is to connect the USB cable to the phone and see if the phone is prompted to charge. If the data cable of the mobile phone is connected to the computer and only displays charging, but cannot be operated on the computer, first of all, it means that the USB interface of the computer is fine. As for why there is no response on the computer, it is mainly because there is no driver or phone settings installed on the phone.

If there is nothing wrong with the phone after the data cable is connected to the computer, then either the data line is broken (this is usually rare, unless the data line is flooded or broken, etc.). , or the computer's USB interface is not available. It is common that the USB interface of a computer is not used, which is generally caused by the following reasons:

Some desktop computers have USB ports on the front and rear of the chassis, but the front USB interface needs to be connected to the motherboard. If the USB cable on the front chassis is not plugged into the motherboard during installation, the USB connector on the front of the computer chassis is not available. So if this happens, you can try to connect the data cable to the USB connector on the back of the desktop chassis (the back USB interface comes directly from the motherboard, usually no problem).

In addition, to check if it is a USB interface, you can also test the usefulness of the interface with a USB disk or a USB mouse. Another possibility is that the USB interface is blocked in the BIOS setting. Usually, Internet cafes will use this way. If there is no response when connecting a computer with a mobile data cable in an Internet bar, this is probably the case. You can consult the Internet bar attendant.

two。 After the phone data cable is connected to the computer, the phone shows that it is charging.

If the phone data line is connected to the computer and the phone interface shows charging, then this has eliminated the problem of the computer USB interface and the phone data line, usually the driver or the phone setting problem. First of all, we need to check the phone settings, especially Android phones. You need to enable "USB debug mode" in the phone settings before the computer can recognize it, so the first step is to check whether USB debug mode is enabled in the phone settings.

After turning on USB debug mode, if the computer still does not recognize the phone, please install any aids such as Pea Pod, Master Zhuo or 360Mobile Assistant in your computer. In the network state, open the tool, generally will detect the mobile phone, and then automatically install the corresponding mobile phone driver. If it is iPhone, please download the 91 Mobile Assistant or iTunes tool.

Generally speaking, today's smartphone data cable does not respond to the computer is mainly due to the above two situations. Of course, there are also some very small possibilities, such as mobile phone problems, mobile phone USB data interface damage and so on. But this rarely happens. Generally speaking, there are few reasons why the mobile phone data line does not respond to the computer, the main reason is to pay attention to troubleshooting.

At the end of this article, I hope it will be helpful to you.
