In researching your error, it looks like this could be caused by several issues. If you find yourself looking for an inside chore for a few minutes, you might give the following a try.
1. Did you recently install another USB device on your PC? Scanner, printer? If so, sometimes the new devices conflict with other devices.
2. If not, is your camera attached via a docking station or do you use a cord to plug it in? If you use a cord, they can go bad and can cause this issue. If you have a spare, or can steal a cord from another device, try using that and see if it's the cord.
2.5. Do other USB devices, like an MP3 player, or thumb drive work on the USB port in question? If so, then we have a cable or camera issue.
3. Have you tried connecting your camera to another PC? If the other PC recognizes your camera, then we know its your computer.
4. Have you tried plugging the USB device into another USB port? There could be a connection issue with the current USB port. I had read that you could use a cotton swab with a tooth pick or slim tool, put some WD-40 on the swab and clean the contacts of the USB port. They can get dirt and grime on them. I would probably unplug the PC before doing this step.
5. I also read that turning the computer completely off, unplugging the power cord, holding the power button for 10 seconds, then plugging the power cord back in, and booting up might help. This has never really fixed anything for me, but you can give it a shot.
The other things I found talked about chip sets and USB driver reinstalls. If you feel comfortable doing those types of things, then that may be an avenue.
I hope some of this helps. If not, it gave you something to do before having to get back out in the cold.
