Power Surge on Hub Port :-(

Specs: Windows XP

Hi all, I'm wondering if anyone can help? Today i bought some weight watchers itracker scales... (too much choccies over easter!) the screen plugs into the computer by a usb lead and you can track your progress... Well when i plug it in i get this message:
A USB device has exceeded the power limits of its hub port, For assistance resolving this problem click this box.
I clicked the box and all it tells me to do is unplug the usb lead and reset the usb port.
:-( I'm a complete dunce to this stuff! So what iv'e tried so far:
restart computer
swap things around in the usb ports (LOL) needless to say this hasn't worked!
I also have my keyboard &mouse plugged in they are working fine though... The computer is a HP compaq

Any help would be really appreciated!

The most likely thing is you're plugging it into a USB port that can't work properly with the device. Your device may require you plug it into a USB port that can supply the max 500ma of current a USB port can provide. If the device has an external power adapter that plugs into the device as well, you must plug it in.

Troubleshooting USB device problems including for flash drives, external drives, memory cards.

The only other thing that can cause the Power Surge message is when you have added on a USB wiring adapter that plugs into a header on a desktop mboard than has 5 wires for at least one USB port, and the use of the 5th wire is not compatible with the use of the fifth pin for that port on the mboard, and in that case you usually get the message even when nothing is plugged into a port in that USB wiring adapter's ports.

The device should not trigger the message when it's plugged into the built in USB ports that are directly connected to the mboard - those built into a laptop, or those on the back of the computer where most of the ports are on a desktop computer.

You are MORE LIKELY to get the message if you plug it into a port in a hub that is connected to only one USB port built into the computer. Did you read ALL the info at the link I provided ?
