I've been meaning to ask the same question... except in my case I have a Kodak... well my camera was uploading pictures just fine then one day it wouldnt upload them anymore. I uninstilled the kodak software and reinstalled it a number of times and nothing. The kodak software works just fine, the computer recognizes that my camera is connected but the software does not recognize the camera is plugged in. I have no clue what it could be either. I have thought about getting a card reader but I just figured there should be an easy fix since it was working just fine.
