Well, I found a temporary fix for the camera, anyway! I was looking through the after Christmas sale ads and saw something called a Digital Concepts SD Card Converter Drive. Since it was on sale for only $7.99 John had me run out and grab one, (Radio Shack is really close by and John is on call till tomorrow still).
We lucked out, it happens to be something the USB drive likes, because we were able to take photos and put the SD card into the converter drive and voila, photos on my computer, with no freezing it up. :) Not bad, and under $10.00 :)
But any info on how to check or fix USB ports (in the long run we might need to fix the problem), would still be appreciated. :)
