USB device using FTDI D2xx driver stops working with Mac OS update

I have an external USB device (a radio) that uses and FTDI D2xx driver https://ftdichip.com/drivers/d2xx-drivers/ to communicate and program utilizing the software Chirp. Every time the OS updates it quits working. It seems to be a FTDI driver issue and online groups talk about various fixes that worked under various operating systems. My machine has been updated many times. This time I'm just lost and can't get it to work. HELP PLEASE

iMac 27″, macOS 10.15

You need to contact the USB Radio manufacturer. Good luck!
