TL-A3 - Nothing detected with Find my laser


I was using a k40 engraving machine with a Topwisdom TL-A3 controller and it worked pretty well.
Now that I change my first computer for exactly the same model, the machine doesn’t connect with Lightburn.
I’m on windows 10 with DSP licence, drivers are installed. I try with Autolaser and it connect without problems.

Any ideas ?
