Fret not, dear Richard.
I have four different USB cables in my cable drawer:
1. iPhone USB cable*
2. Nikon Coolpix S10 USB cable
3. Nikon Coolpix 995 USB cable
4. Nikon D50 USB cable

After about two years, I finally realized I should put labels on the cables. I used regular mailing labels wrapped in clear mailing tape.

* And because I use a bumper on my iPhone, there are actually two different iPhone/iPod USB cables that are not interchangeable.

So many wonderful ideas and suggestions. It may be Thursday before I get a chance to look closely at it - so I just wanted to show you guys that I appreciate the input and am staying with it albeit a bit delayed.

Be back soon...

All fixed... :D

I sat down fully prepared to try any number of suggestions one after the other.
I was armed with Forum responses and with my new "iPhoto '11 Missing Manual" by David Pogue.

Pogue actually had a heading "iPhoto Doesn't Recognize my Camera"
One suggestion was to try a different USB port. That was easy to comprehend and thus a good place to start, I decided.
LO and behold: It worked so I never got to the next step which would have been to work through suggestions on this Forum.
Turns out the USB port on the right side of my keyboard won't work, the back of the computer will as will the left side of the keyboard.

I am happy that the USB port on the left side of the keyboard works because it is a lot easier to get to than the USB in the back.

Thank you, everyone, for your input and support. Because of that I was confident as I sat down that this was solvable.
I had not expected it to resolve quite so quickly and easily, but I guess that makes up for the many times when it has been the other way around!

Now I just have to remember what project I wanted to accomplish with this download - ha!

Hmmmmmmmmm. The USB ports on the back of your Mac are powered. Many devices that connect to your Mac require a powered USB port. Apparently you camera does which doesn't surprise me. But I was under the impression that both USB ports on the keyboard weren't powered.

So why would one work and not the other?

But you've got your problem solved which is all that matters.

Possibly one port on the keyboard is not functioning.

I still would like some clarification about the keyboard ports. I thought they were not powered. I know I've tried plugging in various devices only to be told that the device required a powered port. That's why I've always assumed they weren't powered.

If the camera requires a powered port (and apparently it does) then neither port should work. But if the camera doesn't require a powered port then both should work unless one is faulty as you suggest.

I've checked at the Apple support forum to see if I could find a definitive statement about the keyboard ports concerning powered vs. non-powered but I can't find anything.

In addition to the power supplied at a USB port, there are high-speed and low-speed ports. That's independent of whether the Mac supports USB 2 or only USB 1.

It's hard to understand why a camera would need power from a USB port. It's got its own power.

Anyone else in SMUG have this particular camera model to test?

Next time you plug the camera in give this a try. Plug it in to the original USB port that didn't work and see what happens. I'm betting there was a temporary issue.
