That's a shame! I was excited to have such an easy solution for a
decidedly annoying problem... I can't help much on the Windows side of
things unfortunately. Are the devices off-the-shelf products or are they
something custom built for your application?
In the past I have used this udev rule to create symlinks that helped me
map out the devices. If you use the PROGRAM={} you can run a script that
produces the name of the device instead of using the symlink.

# udev rule for AWARE MCCM G2 serial interfaces
#identify FTDI devices with VID/PID pair and create a convent symlink in
/dev
SUBSYSTEM=="usb", ATTRS{idVendor}=="0403", GROUP="plugdev",
SYMLINK+="%s{product}_%s{serial}"

I was trying to ditch the pyserial lib specifically because of
problems on Windows, notably:

But since I have a workaround, I'll stick with that until someone
tells me how to do it with libftdi...

I'm running in an environment where there may be multiple FTDI
devices plugged in. And I'm running other code (a Modbus
library) that needs to know the port names (i.e.
/dev/cu.usbxxx on unix/osx or COMxx on Windows) for each FTDI
device.
I'm using ftdi_usb_find_all() (via pylibftdi's
Device.list_devices()) to get the list of serial numbers --
that works. But I need to know the port names for each device.
Is there a call in libftdi that will produce the port name for
a given serial number?
TIA.

Pyserial can do this.

Not sure how well it works on osx/windows but I know it works on
Linux.
