I have tried with the device numbers as they appear in lsusb with the 0 in front USB084 and without.
I also tried -S /dev/ttyUSB084 as per jstefanop's post, 'for linux it will be /dev/ttyUSBx' however the example is '-S MLD:/dev/ttyUSBx'

Is there something I am missing?

The ttyUSBx number does not match the bus device ID. Navigate to the dev folder and search for ttyUSB*. You could just try ttyUSB0 and so on ttyUSB3... usually moolanders show up as the first usb devices and newpacs do not show up there at all. If you have been trying to hotplug them the number could change.

Cheers for the help,

Yes I do hot plug the moonlander's and their hub from the Pi4 and Pi3 between posts however I do an lsusb and update the new device ID.
Tried -S /dev/ttyUSB0-3, -S /dev/tty0-3 without cgminer running. Even tried this on the (control) Pi3b+; clean Raspios, bfgminer_5.4.2-futurebit2_linux_armv6 and dependencies. NO DEVICE FOUND
ls of /dev folder produces TTY, TTY1 - TTY63 (in caps) no ttyUSB.
Without going too far into the weeds I changed the GeckoScience --usb : device numbers to wrong numbers and and all devices worked. Thanks for educating on the difference between port and device ID Lercker.

dmesg | grep tty was the only way I could figure out which USB# was what.
