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?

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!

Just to confirm, are you using the EOS Digital Rebel XT like the user in the first post, or do you have a different model?

I have a Cannon Power Shot A 2300. My computer was fine with it until yesterday and suddenly no longer recognizes it. I have tried all the USB cords I have. Any suggestions?

Welcome to the Canon Community Forums! The PowerShot A2300 is a fairly recent model, so there shouldn't be any "incompatibility" issues. You mentioned it worked until yesterday, and that makes us wonder if maybe there were any recent updates to your computer, like Windows updates (or other program updates). Sometimes another program might update and cause unintended conflicts.
Usually if that's the case, it's a pretty straight-forward fix, but it's something that would be to walk you through over the phone. We suggest reaching out to our 100% free, US-based team at 1-800-OK-CANON (800-652-2666) anytime between 10am and 10pm Eastern Time during the week (Monday through Friday), excluding holidays.

I have a Canon 6d that will not read on my Macbook Pro when plugged in through the USB. It used to work a few weeks ago, but now it stopped working. I dont think anything has changed nor have I changed anything. The USB that came with the canon from original purchase has literally only been used once so It cant be the USB cord. I have researched everything and dont know what to do. Need some advice/suggestions/everything.

USB cords can be defective from the start, die after one use or a thousand. The USB cord that came with my iPad worked once to charge the iPad, suffered no physcial trauma, but never worked again. With an issue like this try a different port on your computer AND then a different cord. You can also try connecting another USB device to your computer to see if it is recognized by that port.
