Image capture/finder/iPhoto not recognizing devices

I have a 13" Aluminum MacBook running Snow Leopard. For the past few months I haven't been able to get iPhoto, Finder, or Image Capture to recognize either my iPhone (although iTunes recognizes iPhone) or my Fujifilm FinePix. I had some other OS issues so I ran the Snow Leopard repair disk utility. I've also installed the Fujifilm FinePix Viewer to try to get the photos off my camera, and it doesn't detect it either. It's not the USB ports, they all work fine with my backup drive. It's not the devices because they all show up fine on the old desktop PC (yuck). Software is up to date on both the MacBook and the iPhone. Any suggestions? Thanks so much!
