Just want to add to this ticket so that the solution is included.

This bug is confirmed fixed for the upcoming 3.0.3 release, and the Enttec DMX User Actors I have posted to the Plugins Page are not affected by this issue in the current release.

I fixed the problem -  I tried Qlab a it "hold me" that there were two files in my library that i should delete to make the DMX USB PRO interface work agin i did and it worked ... 

It was this two...

It is so helpful. I will research a bit more and then will decide.

All my best,
