Rugbymonk,

I had the same problem when I changed USB ports.  All I had to do was uninstall and reinstall my printer and one of my digital cameras.  As soon as I did that, all USB ports work fine! Try that and see if it works for you!

It worked!

That was fantastically simple.

Thanks very much!

p.s.  Have you ever used a "splitter" (for lack of a better word) to permit several USB's devices into one port?  I saw one at Radio Shack....
