This article will explain in detail what to do when the usb interface of the win7 system does not respond. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

1. The front USB interface of the computer chassis is not available.

Many people's computer is the host front USB interface can not be used, the host front USB interface is connected to the corresponding port of the motherboard through the data cable, if the connection is loose, or the middle data cable has a problem, then the host front USB interface can not be used.

While the USB interface behind the host is on the motherboard, we can try to see if the back USB interface can be used. If it can be used, it means that there is a problem with the front USB interface.

If the front usb interface cannot be used, try this method first:

1. Right-click my computer, click Properties, and open the Properties dialog box.

2. Select Advanced system Settings-hardware-device Manager.

3. Select the universal serial bus controller. Find "UsB Root Hub."

4. Right-click "UsB Root Hub" and select Properties.

5. Select power management and uncheck the box before "allow the computer to turn off this device to save power". And click OK to return, and then restart the computer namely.

2. USB service is disabled by the system

If this service had not been set up, this would not have happened. But there is also a special case, that is, many people have some optimized antivirus software installed on their computers, which can disable the USB service when using these software. At this point, we just need to unban the USB service.

Open the antivirus software installed on the computer and check whether the "system plug and play service" is disabled. If it is disabled, it may cause the USB interface on the computer to be disabled. At this time, we can turn on the "enable optimization service" in the antivirus software, and then unblock the "system plug and play service".

3. USB is disabled in BIOS settings.

In the BIOS setting of the computer motherboard, there is an item to set the USB switch, the default value of this option is on, but if we are not careful, or if the BIOS setting is wrong, it may also cause the USB interface to be disabled. We can check whether the BIOS setting disables USB.

Restart the computer, hold down the DEL keyboard on the keyboard, then enter the BIOS settings, find the USB settings item in the interface, and check to see if it is disabled. As the BIOS settings are all in English, you can look it up directly on the Internet if you don't need it.

4. USB interface damage or motherboard failure

The USB interface is mainly on the motherboard of the computer. If there is a problem with the USB interface on the motherboard, or if the motherboard fails, then the USB interface cannot be used. If it is really the motherboard problem, then we only need to repair or replace the motherboard to solve the problem that the USB interface does not work.
