I may be SOL, but here I go. I want to connect an old SL 16.4.2 Classic mixer to my new(ish) Dell Laptop. It is equipped with a Thunderbolt 3 (?) USBC port. I purchased and a completely unreasonable price the appropriate Apple adapters to get me down to the firewire 1394 cable. As seen on a youtube video, This is supposed to allow firewire devices to be connected to your laptop. I have made the connections, installed Universal Control 1.7.6 and my Mixer is v. 1.50b build 190. But the mixer does not show up in UC. It's possible I may need to uninstall and go through the painstaking process of cleaning all the files out and reinstalling. I guess I will give that a try while I await your suggestions. My fear is that it simply will not work. The odd thing is that even though it doesn't show up in UC, I can see an option for presonus Firestudio in my capture software. But it will not connect. If I delete UC, that option is gone and the only option available is the windows audio. So, something is getting through. I also tried setting the Firewire link ID to zero. Something I found on a similar post. That didn't work.
