That would be ok, but I think in the ideal world it would be better if 
the system told the user nothing and just prepared to use the device. 
E.G. if it thinks its a storage device the system automatically mounts 
it and displays it's contents. The system should only prompt the user 
when it's not sure what to do. If the system is sure it knows what it's 
doing, but it's wrong, then the user should open up some sort of device 
management program and make the changes then.

That would be great.

That sounds like a good idea.
