That brings up a couple of questions.
Are you using Windows XP?
Are you using the Kodak software to detect the camera?
I have been using this camera with no problems for almost a year. I do not use the memory card or anything like that. I simply take the pictures, plug the USB cable into the camera and PC and it automatically detects it and then i get the pics off the camera. Oddly enough, out of nowhere, the PC stopped recognizing the camera. My dad has the same camera and his is doing the same thing. I have tried all the obvious things and even bought a new cable and nothing. Any help would be greatly appreciated.
