Power Surge error message

I repeatedly get the message "Power Surge on Hub Port: A USB device has malfunctioned and exceeded the power limits of its hub port. You should disconnect the device." This is despite the fact that no device is plugged in. It doesn't seem to affect the functionality of the computer as far as I can tell but it is still concerning. Any advice on how to address this?

Hello,

 

 

I guess that this could be your error message:

"Error message when you wake up a Windows XP-based computer from hibernation or from standby: "Power Surge on Hub Port: A USB Device has exceeded the power limits of its hub port"

 

If it is the case, please try below solution:

 

SYMPTOMS

 

When you wake up a Microsoft Windows XP-based computer from hibernation or from standby, you may receive the following error message:

 

Power Surge on Hub Port: A USB Device has exceeded the power limits of its hub port. This error message is displayed even if there are no USB devices connected to the computer.   WORKAROUND loadTOCNode(1, 'workaround'); To work around this issue, disable the USB 2.0-enhanced host controller.

Note When you disable the USB 2.0-enhanced host controller, you lose USB 2.0 functionality. That is, you revert to USB 1.1 functionality.

To disable the USB 2.0-enhanced host controller, follow these steps: 1. Right-click My Computer, and then click Manage. 2. Under Computer Management (Local), click Device Manager. 3. In the Device Manager pane, expand Universal Serial Bus controllers. 4. Right-click the USB 2.0-enhanced host controller, and then click Disable.

Note The name of the USB 2.0-enhanced host controller may vary. 5. When you receive the confirmation message, click Yes. 6.

Close Device Manager.

 

 

I hope that this should resolve the issue for you.

 

 

Please let me know the result. 

 

you can mail me at thumuvikram@rediffmail.com for any further assistance on this issue.

 

I'll be glad to help you.

Power Surge on Hub Port


Some USB devices draw excessive power from the USB port, especially USB scanners. When this happens you need a powered USB hub, connect this to your computer's USB port and connect the USB device into the powered USB hub, you should not have any further error power surge problems.

Power surge on hub port


Try this to find out which one of your components has an issue. Turn off your machine then unplug all of your USB cables. Turn your machine back on and plug in one of your USB cables. Verify the component you just plugged in works correctly and if it does plug in another cable and verify that component is working. Continue these steps until you have the one component that displays the error you have seen. That component is most likely the cause of your issue and should be replaced.

Good luck, Greased.
