Camera not connecting to pc

your camera use a USB Cable 3' A To Mini B - (5 Pin). I recommend
1.- connect to another USB port.
2.- connect to another PC
3.- try another USB cable

You can buy in http://www.amazon.com/Canon-PowerShot-A3100-Digital-Camera/dp/B003ZRQQ26

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. Or you can use any photo cataloging program.

When you tried the other 450d, did you use your cord or the other person's cord? You could try a camera reset. Go into the menu and scroll to "reset"...follow the on-screen instructions.

Your USB cable is fine, I use a generic cable with my A590 with no problems. Connect the USB cable to the camera then your computer, make sure that the camera is set to the view setting instead of picture taking setting and then turn your camera an. Your computer should then see the camera. This is the only combination that works with my camera.

Best regards,

Use a card reader to download your pics.

Hi and welcome to FixYa.

Sounds like your reading right from the manual. <grin>
Try this.
Connect the camera to the computer via the usb cable. Set the mode switch to playback and press the power button, then:
on your pc go to Start>All Programs (or Programs)>Canon Utilities and find Canon Window. Double click on it and it should fire the program. Let me know if you have any problems. If not, feel free to rate my solution.

hi tajmahajr,
yes i have seen many problems . like some people says my digital cam can-not connect my pc or mac.
so dear firstly check your data cable (wire) which is the medium between camera or mac.

What do pictures taken at night/poor light look like ?? if they are an improvment ,
your Exposure/Auto-Light/White Balance settings may be horribly configured.

Firstly I'd try Resetting the camera to default settings by using the settings menu .
>Menu >Settings >Reset default settings

This should eliminate poor settings as a suspect for the problem.

either your usb-port or usb-cable... I had the exactt same problem //LaN
