Power Surge on Hub Port

Hi guys

I see I'm not alone with this problem, but the other suggestions have not worked.
I have a laptop (HP nx6120) which keeps displaying "Power surge on Hub Port"

The exact error is "A USB device has malfunctioned and exceeded the power limits of its hub port. You should disconnect the device"

There aren't actually any devices connected to it.

I have tried:

* DIsabling USB 2
* setting the tray icon to "always hide"

I did find a patch but it seemed Dell specific so I didn't want to risk it on an HP.

Any ideas?

Have you tried updating your chipset drivers?

As a last resort, you could always disable the USB controller.

I found this discussion of someone describing the same problem, they said that the main board in the laptop needs replaced.

The last comment in here describes something they did with the CMOS battery that seemed to solve their problem:

If the new drivers don't fix the issue and the devices work properly when plugged into the ports, you can turn of the error messages:

Go to Control Panel/System/Device Manager/Universal Serial Bus Controllers/StandardOpenHCD USB Host Controller/Advanced tab, and check "Don't tell me about USB errors"

Thanks to bmsjeff and Crash2100.
the "Don't tell me about USB errors" seemed to have masked the problem where the user no longer bugs me.

points shared because I did find the "don't tell me about usb errors" in the link Crash provided, but jeff spelt it out directly"


thanks guys :)

I've got the same issue, but only when I plug my USB memory stick into the USB port. One of them was missing the little plastic guide for the USB port so I super glued one in there, then noticed that I get the error. I've removed it and still get that error. Any idea?
