Hi Rob/David
Actually for the 9100 it always presents them in the right
sequence. ie the first is always the C-IV port. Other USB devices
may of course get in the way of numbering if they are enumerated
first, for which the link/udev approach works. I would assume that
Icom configured the UARTs to always respond in the same order.
I don't think serial-by-id would solve the problem if the 9100
UART response sequence changed.

Since it appears the radio provides 2 USB devices (USB0 and
USB1), the operating system may not "ALWAYS" present them in the
same order.
This will cause no end to interfacing headaches.

If you are running this on a Linux distribution, you may look
into udev rules.
Depending on the USB device, you should be able to find a way
to separate the 2 and provide more descript '/dev/{device-name}
sim-links to make things easier to keep track of.
They may be using the same ProductID and VendorID, so you may
need to dig a bit deeper to find the identifying USB
characteristic to separate them.
