I would immediately be suspicious if the USB cable going from your camera to the PC. There are a bunch of tiny little wires in the cable, and it’s certainly possible that one of the wired broke from being flexed too many times.

Remember that a USB has either 4 pins or 9 pins (USB2 or USB3) and the PC would see the camera voltage on two of the pins but be unable to transfer (or see) data over the other pins.

So try a different cable first.

Next, turn off the PC. Not just reboot. But power down. Turn it back on See if that changes anything.

There are other more complicated options if these don’t work.

Thanks. The cord thing is a possibility I guess. But I turn off my PC every night, so I know that’s not the issue.

Sounds to me like either a bad USB cable like @elbanditoroso wrote, or either the camera or computer changing their minds about playing nice about USB file transfer.

What happens if you plug some other USB device into the computer using the same USB cable? Or is it one with a plug that only fits the camera?

What happens if you try to drag a picture from the computer onto the camera?

And/or you could get a USB SD card reader for the computer. They can be very cheap.

If you are sure the cable is good, is it possible the USB setting on the camera has changed? Did it inadvertently switch from “power and data exchange” to “power only”?

Sometimes the USB on your camera can be in a different “mode” some cameras and phones you have to select what you want the USB connection to do. If the cable works on another device this is probably your issue.

If having problems use the SD card into the USB port to download.
I don’t have WIndows program and it still downloads either way SD camera card in slot or cable..both work fine.

Update. I guess the old PC was going out of date to even recognize my old Kodak Easyshare. Now that have my new PC with Windows 10. I plugged in the camera with the card, recognizes it just fine now. Thanks all.
