How To Fix USB Code 43 Error Problem?

[Camila_Saunders]

The USB (Universal Serial Bus) port is a familiar and extremely handy piece of technology that increases your computer’s versatility. When this old and reliable USB port stops working, it is a huge inconvenience.

We rely on USB ports to run an array of frequently used devices including the keyboard, mouse, webcam, external storage devices, microphones and speakers. We can sum it up to say that a huge percentage of the computer’s external hardware devices run through the USB port.

How To Fix USB Code 43 Error Problem?

Usually, when you plug in an external device to the USB port, Windows recognizes it and installs the set of drivers necessary for internal communication. When Windows fails to recognize the device and its drivers, it displays the error message: Windows has stopped this device because it has reported problems (code 43).

Here are some steps that might help you solve this problem.

1. Insert into a Different USB Slot

There is always a chance that the specific USB slot is malfunctioning. If this is the case, your simple solution would be to unplug the device and plug it into a different slot. There are usually at least two USB slots, so if one of them works, you know the problem is not in your software.

If this does not fix your problem, continue to the next step.

2. Restart

• Restarting your device might help solve this problem.

• Here are the steps to attempting this method:
