[Elecraft] K3 not communicating with PC

[Matt Zilmer]

If there's any doubt which COM port is used by the KUSB, you can use
the Device Manager -> Ports to list all the COM ports.  The one with
Prolific shown is your KUSB.

Sometimes in enumeration, USB-Serial adapters will change COM port ID
from boot to boot.
