When the phone is connected to the computer, the usb connection settings will not pop up.

Many friends found that USB connection settings didn't pop up when they connected computers with mobile phones. I don't know what caused this. Let me tell you the reasons and solutions.

Before talking about the reasons and methods, let's talk about several modes of connection between mobile phones and computers, such as USB debugging mode and MTP mode, which are connected by third-party software. Some modes need to turn on a certain function in the mobile phone, and some need to install corresponding drivers or software, but problems in the hardware itself, such as poor contact and damaged data lines, are not excluded. Then, let's talk about the reasons and solutions.

I. Limited functions

Take Android phones as an example. If you use third-party software to connect your phone and computer, you must turn on USB debugging mode. Only when "USB debugging mode" is turned on and the mobile phone is connected to the computer will the third-party software installed on the computer pop up the corresponding connection setting options.

Second, the problem of driving.

The MTP mode was mentioned in the previous article. The biggest function of this mode is to temporarily convert the mobile phone into a storage device, similar to a mobile hard disk or a USB flash drive. If the phone is turned off, or the phone supports MTP mode, when it is connected to the computer, the mode selection option will pop up under normal circumstances. After selecting MTP mode, USB connection settings will not pop up directly, and users need to manually install MTP mode drivers.

If there is something wrong with the driver, or if there is no driver installed at all, neither the computer nor the mobile phone will prompt. You can download the corresponding MTP driver through the official customer service of the mobile phone or the model of the mobile phone, and the corresponding prompt will pop up after the installation is completed.

Third, the data line problem.

If the USB debugging mode of the mobile phone is turned on and the MTP driver is installed correctly, the mobile phone still cannot be connected to the computer, then it may be a problem with the data connection cable.

Theoretically, the data cable is mainly used as a mobile phone charging tool, but it also supports data transmission. In the process of user's use, with the increase of use time, the data cable may lose its function of transmitting data. Although you can continue to charge the mobile phone, you can't provide data transmission function. There will be no prompt when connecting the mobile phone and the computer with the damaged data cable.

The solution is also simple. The cause of the failure can be tested by directly using the elimination method and replacing a brand-new data cable.
