The user has decided to put the device in a state in which the driver
cannot properly function. If the user wanted the driver to work, he should
select autosuspend.

That is the thing with the forced suspend - it leaves device out of
sync with the rest of the system. If user really does not want to use
the device it should probably be completely disconnected?

Some devices are rather difficult to disconnect (the cabling may be 
inaccessible).

Also, devices can be suspended by software, but generally speaking they 
cannot be disconnected by software.
