When connecting to the usb on Mac laptop I get the error message Device is using too much power and will be deactivated. I have had this camera for 7 years and this has never happened. Removed and reinserted battery, memory card and battery in laptop. No resolution. Cannot upload photos to mac.

It will still be covered by the warranty, take it to an apple repair centre, they will have Apple hardware diagnostics software that will be able to determine the cause of the fault. Worst case scenario will be they have to replace the logic board.

If you are using some sort of USB hub the number of devices you are connecting to that single port may be drawing too much power. Try to determine how much power each device is drawing then ask at an apple store how much power the USB port can supply.

I had this problem today and you might want to check this
from PC's menu = go to my computer right click and select properties
select device manager,
locate "canon camera" which may be under portable devices as mine was
There is either a plus or minus sign next to it. If it is negative as mine, delete this driver. Make sure your camera is off and unplugged before you delete it.
Plug camera in, turn on and the camera should download the driver again.
It worked for me - I'm not technically brilliant but basically, the driver wasn't working correctly.
If you can't find the same settings, call customer service - they were great.

The power adapter could be faulty.
If you get an error message"Insufficient power to operate USB device" when you plug a USB deviceinto the computer's USB port, then this device is drawing excessive currentthat the USB port cannot supply. In case such as this, youneed to purchased a powered USB hub and connect this hub into the computer'sUSB port and then connect the USB device into this powered USB hub.

Consider NOT connecting your camera to your computer.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use iPhoto or any other photo cataloging program.

The USB port can only deliver aprox. 500mA. If your USB device such as a scanner etc. draws more current from the USB port then you will get this error message.
The solution is you use a powered USB device OR use a powered USB hub and connect this to the computer/laptop's USB port and then plug the USB device into the powered USB hub.

Turn off the CPU unplug the power cable and all usb cables, let it sit for about 15-20 minutes. Plug power cable back in, turn on CPU, plug in your usb devices.

To connect to a Macintosh computer: 
1 Plug in and turn on the digital picture frame. 


2 Connect the small end of the usb cable to the usb port on the side of the digital picture frame. 


3 Connect the larger end of the usb cable to a USB port on your Macintosh computer. The Macintosh will recognize the digital picture frame as an external storage device, and an icon will appear representing the device.


4 Drag and drop your photos on to the icon...


5. After you finish, press the eject button, and disconnect the usb cable once the icon has dissappeared


If there is still a problem, try restarting the macbook. and make sure no other programs are running in the background that may interfere with the process. Also, make sure the laptop is plugged in, or the battery power is sufficient.


Hope this helps!
Let me know!

Hi

Try connecting the printer to a different usb port if you have extra port and make sure the connection is direct from printer to your mac

Hope this helps

use a USB port on the back of the PC, not off a hub, or use a powered hub, It cant take more than 500mw of power per USB port, even though there are 2 ports, they may be off the same controller inside the pc. I use a powered hub and have not had that problem ever since. I had a webcam that drew 450 and no other device worked off that port.
