udev rule not detecting my ThumbDV DV3000U

I made the following change to my udev file to get the symlink working on my system. Not sure if this only affects some hardware. The device was purchased in 2018 from Radioworld Canada, though it came with an instructions from FlexRadio Systems dated 2015.

SUBSYSTEM=="tty", ATTRS{product}=="FT230X Basic UART", SYMLINK+="ThumbDV"

Below is the output of udevadm info -a -n /dev/ttyUSB0

It appears your ThumbDV is very old and was not programmed with product information. Contact sales@nwdigitalradio.com and ask for directions to program the ThumbDV™ with the proper fields. Then use the udev rule found in etc/udev/rules.d of this repository.
