I modified the registry to make one of my ftdi cables show up on com14. Both the old port (com4) is listed since it was the last used, along with the new port number com14. Com14 works in chirp to download my radio as expected on win10 x64. Seems ok to me!

Won't this cause us to detect them, but then fail to open them? Or is
the failure just in the detection code above?
