If you're running a GUI, and have trashed some files from the camera (so 
that they're in the recycle bin) they're not really removed from the 
device until you empty the bin. That might hold the device open and 
prevent the system from unmounting the camera.

So if you already haven't, you can try emptying the recycle bin.

I've seen this happen with jump drives and such.
