Win 7 64 bit not seeing 5DMIII. Windows cannot find a driver. Same for my 7D.

Windows is not detecting my cameras. I have a laptop and Desktop (both Win7 64 bit) and the same is happening on both. I plug in the camera using USB cable that came with camera and Windows fails to find a driver. Device Manager shows a yellow exclimation point and shows as "canon camera". I have a work laptop with the same OS and it works fine.

Have you tried re installing the software disk that came with each camera?

Try the automatic USB troubleshooter:
