Thanks for the explanation. I guess that kinda makes sense. One thing
I'm entirely sure about -- I had removed the sw default state setter --
I guess this code still requires then? I was thinking the sw default
state should be set for the devices it applies to, but it seems that if
the master rfkill switch is set to "transmitter off" then one needs to
set the default state (for all USB transmitters etc) to off, correct?
