DMX USB Pro Interface : Better than expected

I use QLC plus for lighting control on a basic desktop machine with minimal Ubuntu installed. I had problems with flickering lights with Enttec open interfaces and decided to upgrade to this. It solved my problems, and contrary to the instructions no additional drivers had to be installed in the Ubuntu machine. I also ran it without problem on a Mac with an M1 processor.

The only issues I had were with the manufacturers instructions. To check or update the firmware and, if necessary reset it, you need additional software, which it turns out has to be EMU light control software. There is a free version of this, but finding it is not straightforward. The manufacturer does have good support, though, and did provide a link to me. You may wish to get over this hurdle before it arrives.
