Okay, Dec 13...then you need the version v3.2.2 (called 3.1.4 in the forum, it's the latest version) in order to connect to your sound board and change its settings without damaging it. v2.2.2 is only needed for the older Obsidian v2 sound board and for making your own LSU (saber sound) files since the converter is only included in the v2.2.2 zip package.
I'll still get the USB 2.0 hub, just in case you still encounter connection problems, also after testing several USB cables and USB 2.0 ports (if included in your system). If that doesn't work either, then it would be better to ask Emory as he might think of other solutions not obvious to us
