Computer won't detect camera

[lyssa615]

All of a sudden my computer won't detect my Rebel XT. I replaced the USB cord but nothing is even detected in "My Computer" or in the Device Manager. I am sure that the USB ports work properly as they work with other devices.  I reinstalled the software it came with and tried changing the communication settings on the camera. Does anyone have any suggestions?

Hello!

To ensure the most accurate information is provided, we will need to know the version of Windows you are using.

Thanks and have a great day!

What kind of USB cord are you using?  I have had trouble with some cords in that past (although usually it does detect my camera and subsequently drops it as soon as EOS utility loads).  I've found that only cords with filters on them (the black plastic cylinders at one end) work consistently.  I'm not convinced it's what causing your issue, but thought I'd bring it up.

I'm assuming you've turning your computer on and off, and the USB port on your computer is functioning properly?  Every once in awhile my comp won't see my camera and it's just a matter of turning everything off and on again.

Hello lyssa615,

The EOS Digital Rebel XT came out before the release of Windows 7 and no drivers are required with Windows 7.  There is a workaround for this as the camera  supports the Picture Transfer Protocol (PTP) driver that is built into all versions of Windows since XP.   The "PC Connect" communication mode on the camera wouldn't allow the camera to be connected instead it needs to be set to the PTP Mode.   

To enable this, first make sure that your camera is disconnected from the computer. Press the MENU button and then use the right arrow key to select the second "Tools" tab in the menu.  Use the down arrow key to select the item labeled "Communication" and then press the SET button.  Use the up arrow key to select "Print/PTP" and then press SET again.  Press the MENU button to exit the menu system.

At this point, you should be able to reconnect the camera to the computer, and the system should recognize it as a digital camera.  You should then be able to use the operating system's built in utilities such as Windows Live Gallery to download your images.

Some USB cords are wired for charging only, others for charging AND data transfer. Try different cords. I have several cords, but only 1 that let's my laptop see my phone. It’s all in the way the cord is wired.
