My galvo fiber laser but Lightburn not recognizing it

I am on the free trail version of lightburn, hoping to transition to lightburn fully (if all goes well), i am having trouble connecting the machine to the software (lightburn) via “find my laser” window and I don’t know the laser controller to do it manually, as the machine came with instruction manual that just refers to EzCad2 and no other descriptions. Please note that I have switched machine on and off a number of times i have also which computer on and off an number of times. Any constructive advise is greatly appreciated!
