Title - Edgport/4 compatibility question

Hello there - I am trying to get some legacy EdgePort/4 and 8 devices to work on Linux using Raspberry Pi OS.

I notice in the kernel. org notes, compatibility with Edgeport seems to be a good possibility.
In dmesg I get "usbserial: USB Serial support registered for Edgeport TI 1 port adapter" but no corresponding ttyUSB0-3 being set up.

I also tried adding a folder into lib/firmware called "edgeport" with some firmware I found online but I get multiple "Cannot send clear loopback command" messages in dmesg.  This did seem to create ttyUSBs 0-3 but I could not use these devices.

I do not have any problems connecting with a few Keyspan USA-49W devices (which are also referenced in the Compatibility section in the notes) so I think my machine is good.

Apologies in advance - I am not in anyway a Linux expert.

Any guidance or tips would be appreciated!
