State-Changed-From-To: open->feedback

State-Changed-When: Thu Mar 22 02:47:51 UTC 2007
State-Changed-Why: 
USB has always tree structures and any devices except hubs
are leaves of the tree. This means that you can remove any device without
disconnecting any other devices.
On the other hand, ieee1394 allows daisy chains and you may sometimes
want to remove a device between the host and a leaf device which is
mounted on the host. The current default setting allow to remove physically
such intermediate nodes without unmounting filesystems.
