Power Surge On Hub Port

Lately, I have been receiving an alert in my computer:

Power Surge on Hub Port

Power Surge on Hub Port

A USB device has exceeded the power limits of its hub port. For assistance in solving this problem, click this message

I don’t have any USB devices plugged in my computer except for my HP DeskJet F300 printer, I disconnected it. Still pop up alert appears again telling me to click the message for assistance. When I did, it just said, the port was not reset properly. If you wish to use the port, please reboot. So I tried rebooting, then it comes up with an error Unknown USB device. I tried rebooting, but it does not change anything.

I have 4 USB 2.0 Ports at the back of my CPU and 2 more USB ports in front. I tried to insert a USB disk to the port and look for its drive in My Computer, but no drive appears.

How can I reset the USB hub to avoid the error, or is there any way to stop this error from appearing?

The Operating System I am using is Windows XP Pro. It is really annoying because the error keeps flashing on my screen. What are the procedures in order to avoid seeing it or to fix it completely?

Please send me any suggestions or help.

Thanks.

Hi there!

The error message Power Surge on Hub Port is stating that the device connected to the USB hub is drawing more power than the Hub is designed to supply. It can be caused by an unsupported device or damaged hardware. First of all, check if the printer you are using is self-powered i. e. Have its own power cable or determine if it draws power from the USB ports. If it draws power from the USB, check if its power requirement exceeds the standard USB power limit (high 500mA) per Hub.

If it is self-powered, the problem may be somewhere else. It may be that the port is damaged or short-circuited at some point. Or maybe, the problem is within the printer data cable that was damaged or short-circuited. If the USB disk is also not recognized, then the port may be permanently damaged. Try the USB disk to other ports to see if it works. Try disabling all the USB Universal Host Controllers in the device manager and enabling one by one with USB devices connected to USB ports to find out which HUB controls the faulty port. Then keep it disabled to see if it solves the problem.

See if it helps.
