USB interface Not responding to the solution

⒈) Some computer chassis front USB connectors are not available

Have found many friends the so-called USB interface can not be used, only the user uses the USB interface on the front of the chassis, but the USB connector on the chassis is only available when the USB cable on the chassis is connected to the corresponding interface on the motherboard, and in many cases it is forgotten to connect the USB connector cable on the chassis to the motherboard on the machine. The USB connector on the front of the chassis was found to be unavailable. If we are encountered before the USB interface is not available, you may wish to connect the rear of the chassis USB interface, the rear USB interface is provided by the motherboard, the general problem can be solved.

⒉) system disables USB service

Generally if nothing has been set up, this situation will not happen, but some friends may like to use such as the Golden Hill defender or 360 Guardian optimization system, disabled USB service, the USB interface will also be unavailable.

System Plug and Play service is disabled causing USB not available

Solution: If used well, just optimize some system projects caused by problems, most of which are disabled by the USB service caused by the solution, you can stop the Golden Hill Guards or 360 Security guards boot optimization service items check whether some key system services are disabled, found the boot, Or use the Golden Hill Guardian optimization recommendation, or not friends can consider the System Restore or reload system.

⒊ the USB feature is disabled in the BIOS setup

There is a USB control switch in the motherboard BIOS, which is turned on by default, and if the BIOS or BIOS error is set incorrectly, the USB interface may be disabled, so if the above situation is excluded, we might as well check if the BIOS settings disable USB.

Solution: Restart the computer, press the Del keyboard, you can enter the BIOS settings, and then find the USB setup items, because all is English, I am not very good here to explain

⒋) USB interface damage or motherboard failure

If the above three cases still do not solve the problem, then you need to pay attention to the USB interface failure or equipment failure, such as the user asked above, the resulting problem may be a U disk problem, so we may want to take a few more USB devices to try, if a number of devices, such as mobile phones, u disk and so can not be used, Or someone else can use the computer, their own is not, it may be the USB interface damage, we can try again after the host of other USB interface try, still not, most of the motherboard problem, the proposal to take maintenance.

It can be concluded that the computer USB interface can not be used mainly for the above four causes, the elimination method is also not difficult, in addition to remind everyone in the USB device transmission data, do not unplug the device directly, this may lead to USB device problems, and finally hope that everyone can solve the problem like USB interface can not be used
