The “Power surge on the USB port” error is possible mainly due tothree reasons:

There are only a few cases when a software-related issue might cause this error. Let’s discuss.

Check for Shorts on the USB Device

The best way to rule out a shorted device is totake it to another computerand see if it works there.

In case the error pops up on the second computer too, there’s your answer — thedevice has the short, not the ports.

If that’s not possible, unplug all the USB devices from your system. Then, plug the problematic device into all the ports (front/rear) one after another.

You’ll easily figure out if it’s the device or the port that is causing issues.

Also, trychanging the cableif it’s a removable one. A defective cable can cause a short when you wiggle it a certain way.

Look for Shorts on the USB Ports

Once you are done with the device, it’s time to check for shorts on the USB ports.

While at it, also inspect if anypins are broken/damagedinside the USB ports.

Last but not least, check the prongs on theIO shield.

Resolve the Power Issues

Although rare, the error is also possible if you have abunch of power-hungry USB deviceshooked to your system.

In such cases, the USB controller fails to meet thepower requirementand throws the error. Please check if reducing the load resolves the issue.

If that’s not possible, the best bet would be touse a powered USB hub.

Sometimes, aUSB 3.0 deviceplugged into a USB 2.0 port may cause a power surge error too.

This is because USB 3.0 devices draw up to 4.5 watts of power which is almost double the capacity of USB 2.0 (2.5 watts).

So, if your device is 3.0, connect it to the 3.0 port. It is generally theblue-colored USB porton your system.Refer to your motherboard manualto know more about it.

Try These Software Fixes As Well

Some users even reported they were able to sort out the error with these two fixes. You may try it as well.

If nothing seems to work, you probably have a bad USB controller. Please consult your manufacturer formotherboard RMA(if it’s still under warranty) or take it to the repair center.
