              USB hot plug _can_ work with jack:

            right. if the software notices signals on D-bus that
              the device is going away, then it stops using it in a way
              that causes ALSA to get locked up, putting the process
              into an un-killable state. 

            
            it would be nice if ALSA could be fixed to not do this,
              but it would also be nice if key software like JACK would
              pay attention to device state information too.

            
    Since former is not necessarily in our immediate control, any hope
    of latter being implemented by those on this list who are in
    control?

    
    Best,
