Downloading when we try to download pictures to computor, computor displays a usb device has exceeded the power limits of its hub port, this only displayed when camera is plugged in

Simply put its what it says.

you have too many devices drawing power from the USB ports of your laptop.

A fix for this is to use a USB hub but it MUST be one with its own power supply.

Windows display this message when a USB device is short-circuited. Try another USB cord or connect the usb to the port at the back of your pc. If it does not help then the problem resides in the printer. I will not suggest to dismantle your printer as there are no user serviceable parts inside.

Possibly a short in the camera, cable, or the port itself. Recommend trying another port. If that doesn't help, then please see the following blog article, as it describes the use of a card reader as a much easier, faster, and less error prone way to download your photos. In fact there are several important reasons discussed in the article for using a card reader vice downloading from the camera. USB Card readers are also very inexpensive these day, with cost virtually not an issue:

Use a powered hub, one that has it's own power supply.

This error occures when a USB device draws more power than the USB port can supply.
To fix this problem, purchase a powered USB hub. Power up the hub and connect it to the laptop's USB port and then plug the USB device into the powered USB hub.

Some USB devices draw too much current from the computer's USB port and you get an exceed power error message.
To get around this problem, get a powered USB hub and connect it to the Computer's USB port and then connect the troublesome USB device into the powered USB hub.

The Safely Remove Hardware icon list all removeable devices regardless whether it is a USB or PCMCIA or a removeable CD/DVD drive etc.
To get around the problem with your USB device that exceeds the power limit of the computer's USB port. Get a powered USB hub and connect it to the computer's USB port and plug the USB device into the powered USB hub.

Plug the USB lead directly into the computer, not via a hub
