My Computer (Gateway with Microsoft XP) does not recognize when I plug in my camera (also a Gateway). It is not the USB port. Any suggestions, Microsoft nor Gateway were bery helpful to me.
If the camera was being recognized but now it's not, it's possible you might need to uninstall the drivers for the camera and then plug it back in and let the PC "find" it again. Don't take this as gospel, you should only do this if you know what you are about.
I assume the camera software was installed on the PC as-recieved? In any case, do you have a manual that tells you how to install? If you do, look for a troublshooting guide.
