When my daughter plugs her camera into one of the USB ports on a computer, we get this message:

"A USB device has malfunctioned and exceeded the power limits of it's hub port. You should disconnect the device".

We have tried several ports, same result.

It used to work, another camera works fine on the same port.

What is the issue?

Try this :

1 :Delete all the USB ports in the devices manager.
2 :Restart the computer to let XP install all the USB ports again.
3 :Go to the first USB port and right click on it and go to properties.
4 :On the advance tab click on '' do not show warnings"


Takes care of the problem in most cases.

be sure to check the camera in another computer. It could be shorted and not working via USB any longer.

Have you also got an external Hard drive or Flash drive connected to one of the USB ports?  
If yes, try temporarily disconnecting it & see if that resolves the issue.

Or a module such as described here>

i suggest to use a powered usb hub, like this  : http://www.belkin.com/IWCatProductPage.process?Product_Id=158910
then you avoid completely overloading (and burning out) of usb controllers

The usb interface on the camera is failing and drawing too much current from the usb port. While a powered hub may work, It may eventually destroy the port or burn it's interface out.
