If your other devices aren’t using specifically 2232H chips as serial ports, you can use a kext that matches only that VID/PID pair.

Not that I’m aware of, but you could try asking on Apple’s USB developer mailing list or developer forums.

IMO the right thing would be for device vendors to use a custom VID/PID when the FTDI chips are not used as plain serial ports, and supply the necessary inf files/kexts/udev rules to map the wanted functionality.
