Dell Latitude D610 -- problems with autorun (continued)

Yes all three of them connect by USB. Two of them are small enough where they don't need power supply but my large one does need to be plugged in. I tried all of them on my brother's computer and they work fine. I have plugged my camera and my mp3 player into the same USB slots and they seem to work fine.

I tried the advice of using Win Ex and waiting about 5 minutes with nothing showing up. The only way I was able to open these drives lately is to manually open them by going into my computer, manage, and so forth ..... I can't see any of the drives in My computer (on my computer. On another computer it seems to be fine). The last thing I should mention is when I go to "remove hardware safely" it shows up MOST of them time.
