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 verify if reducing the load resolves the issue.
