This indicates that your programming cable has a chip that identifies itself as being a Prolific type chip. If it is the older PL2303XA / HXA chip it is no longer supported by drivers supplied by Prolific. What can be done to get it to work on Catalina and older macOS is to purchase a 3rd party driver (that is what I did here for my MacBook running Catalina). https://www.mac-usb-serial.com/ For Big Sur you will probably have to get a programming cable manufactured with a different USB-to-Serial chip (FTDI, WCH, Silicon Labs, etc).
