[Elecraft] KIO3B usb com port not communicating

[Rajiv Dewan]

Hello all, especially Don,

  The last tip helped make progress.  I unplugged the P3 connected via 
the RJ45 jack and suddenly my USB/CAT came back to life.

   And, this disruption is repeatable.  Plug the P3 back and again it 
stops working.  Unplug, works again.

   Now, I will look to see what is up with the P3.  I checked the 
firmware on the P3.  It is running the latest.

   Raj
