First install the software that came with the camera. Lost the CD? goto this link and get the software and drivers for free.

After install, connect the camera to the PC and switch it on. if the software does not start automatically, start it by hand and put in the settings it should startup when the camera is connected.

I did search with a name of a camera, but if you have a microfilm scanner, go here for the software and drivers:

Microfilm Scanner 400

Probably your memory card is full, you should erase some pictures from the camera and it will work. It happened to my Canon G9 . I erased some old pictures from my memory card and the message Communication Error disappeared.

Check the right strap lug and see if it is loose. It is a well know problem with the G9 that the screws that hold it onto the top cover come lose and fall into the camera, causing many different problems is they short out parts of the circuit

In order for your computer to recognize your camera you must install the included software. After that it should work just fine.

The problem I believe is the sequence or flow of the connection.
With the camera turned off. Connect the USB cable to a computer USB port and the other end to the camera digital port turn the camera on by using the "Playback" button here is a diagram

You know there is an easier and better way of transferring picture files and that's by using a memory card reader. A memory card reader plugs into the USB port of a computer and the camera memory card is inserted into the reader slot. The computer then looks at this as an external Hard Drive. Both methods will need you to format the memory card after the images have been downloaded to the computer. Formatting the memory card in the camera in which it is to be used will clean the card and making it compatible with the camera both the camera and memory card can then communicate without errors.

Definitely worth fixing, the G9 is an amazing camera and many will argue it is better than most of the other models that came out after. Since you have a Powershot, you can have it repaired through www.camerasandparts.com They just deal with the Canons and they are not expensive at all. It runs $89 for everything if you just get their lens error service package. They cover parts, labor, servicing of the whole camera, with shipping back included for $89. The best part, they do outstanding work on the Powershots. If you're going to have it serviced, I would go through them. Ultimately you'd need to decide if it's worth the $89 to have a good backup camera, if not I'll take it off your hands. In all honesty, the G9's are great cameras, don't think twice. Have it serviced and enjoy the camera again. That would be my advice.

Use a card reader to download the pics to a folder you create on your desktop. From there, you should be able to import them to any program you wish...even iPhoto.
