Just looking at the error message, anyone could assume that one of their peripherals has a problem, but this is rare and most operating systems are to blame. In this article, we’ll take a look at why this error occurs, how to fix it, and if all else fails, what alternatives we have.

Apa Itu Error Surge on the USB Port?

There is a limit to the amount of power or power that a USB port can provide. All USB 2.0 ports can supply 500 mA of power, which translates to a maximum power of 2.5 W. For USB 3.0 and 3.1, the values ​​are 900mA and 4.5W.

USB devices are designed to operate within these limits. However, if you buy cheap headphones that are sold at a very low price, the internal circuits may not meet these restrictions. For this reason, it may start consuming more power than the USB port can support.

If this happens, the Windows operating system detects a potential overvoltage in one of your USB ports. Then the port will not start and your operating system will automatically turn it off. Even so, the damage may have already occurred before the operating system detected it.

So here’s how to fix a USB port overvoltage error in Windows.

How to overcome the overvoltage at the USB port

1. Find the root cause of the problem

Because the operating system disables the USB port that is experiencing peak power, make sure that any of your devices are automatically disconnected after the error message appears. If it finds it, try disconnecting it from the connected USB port and see if the problem goes away.

If none of the devices are turned off by the operating system and the message continues to appear in the lower right corner of the screen, start disconnecting the other devices connected to the USB port one by one. If the message stops after disconnecting a specific device, that device may have caused the tip.

To confirm that the tip is caused by the device, not the port, connect the same device to another port and see if the error persists there. If the tip appears on other ports, then you can be sure that the device is the cause of the problem. You can also connect it to a computer or other device just to be sure, but the result will probably be the same.

After checking it, you can disconnect the device or replace it with a new one. However, if the problem persists on only one USB port and the error persists even if no device is connected to the computer or a single USB port, follow the steps below.

2. Change the Dari USB Controllers power management settings

This fix is ​​useful if the error message keeps popping up repeatedly on your computer. By default, your computer can turn off the USB controller if it starts consuming too much power, preventing the screen from displaying an error. However, if you turned it off before, the error message still appears on the screen because Windows failed to turn off the port, which increases the power.

Therefore, enabling USB controller settings can help you resolve the issue. To do this, follow these steps:

Change the power management settings of Dari USB Controllers
  1. Right-click the button Windows Start and select Device manager.
  2. Expand category for Universal Serial Bus Controller.
  3. Right-click the first USB controller driver and select property.
  4. Navigate to the tab Energy management and check the box Allow your computer to turn off this device to save power.
  5. Repeat this process for all drivers.

If you enable this setting, Windows will turn off the USB port during a power outage. This should prevent the error message from appearing again and again. However, this does not address the root of the problem. To resolve this issue, you must apply the following fix.

3. Update or reinstall the USB driver drivers

Obsolete USB controller drivers can also cause the power port error on the USB port, even if it does not have a hardware problem. To rule out this possibility, consider updating the USB controller drivers. To do this, follow these steps:

Update or reinstall the USB driver drivers
  1. Open Device manager by right-clicking on the button start in the lower left corner of the screen.
  2. Expand category for Universal Serial Bus Controller.
  3. Right-click on any driver and press Update the driver.

Repeat the same process for all drivers to see if the problem goes away. Alternatively, you can right-click on the driver and select Uninstall Device to remove it. After deleting everything, restart and the computer will automatically install the new drivers. If none of these fixes work, try the next one.

4. Use the USB Troubleshooter Help

Recent versions of Windows do not include a built-in USB debugging tool. Microsoft had a USB debugging tool on its official website, but it no longer exists. To download the utility, you must rely on third-party sources.

Use the USB Troubleshooter Help

You can download it from the official website Majorgeeks by visiting the troubleshooting download page. Once downloaded, click on it and the troubleshooting tool will start scanning for USB port issues. The on-screen instructions will guide you through the repair process, if found.

5. Make sure the issue is not hardware related

If none of the above solutions resolve the issue, you will need to request computer service from your nearest technician. There may be a short circuit on the system board or another overvoltage connection.

Conclusion

Here’s how to get rid of excess power on your USB port. When the problem persists even after the fix is ​​applied and not even the technician can fix it, you can buy an active USB hub.

Using this, your device will be able to use the power it needs to operate, preventing overvoltages on the USB port. If you are going to buy it, make sure it is well made and comes from a reputable company.
