I hope you can read it carefully and be able to achieve something!

1. When the setting is plugged into the USB interface of the computer, if the device cannot work properly or can not be used, it is recommended to change the USB interface, or plug the device directly into the USB interface behind the computer chassis to try to solve the problem.

The 2.BIOS setting disables the USB feature

One of the BIOS settings on the computer motherboard is to set the USB switch, and the default value of this option is on, but if you are not careful or if the BIOS setting is wrong, it may also cause the USB interface to be disabled. You can check whether the BIOS setting disables USB. You can 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.

3.USB connector 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 there is a failure on the motherboard, then the USB interface cannot be used. If the problem is really the motherboard, then the problem that the USB interface cannot be used can only be solved by repairing or replacing the motherboard.

4. USB service is disabled by the system

This will not happen if this service is not set up, but there is also a special case, that is, many people have some optimized antivirus software installed on their computers, so when using these software, you can disable the USB service. At this time, you only 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".
