I am having the exact same issue. I have tried a fresh Ubuntu 20.04 LTS install and the newest Lightburn and it detects nothing. I made the permissions changes in udev, but the issue is the VID:PID.
I even tried running as root out of frustration to make sure that it wasn’t a strange permissions issue.
In lsusb it shows the same ID as yours: ID 9588:9980

I did end up installing EZCad on a old Windows machine and I was able to burn stuff, but it shows up in Device Manager as 9588:9899. I also tried what you suggested, swapping after starting on Windows, but that did not work for me, it still shows up as 9588:9980 in lsusb.
I see in the drivers folder that the .inf has both product IDs:
I did not try the Windows version of Lightburn, since that laptop is old and out of date, so I did not want to connect it to the Internet to get the trial to run.
If you or anyone else has any ideas, please let me know. I have a fair amount of Linux experience, so I would be glad to work with anyone to try and debug this.
I already run my diode laser on Lightburn in Linux, which I love! I just bought the fiber and it would be a major bummer if I have to go back to Windows/EZCad.
