I've attached a screenshot, is this the information you need? for the "unknown USBCOMM" thing?
Hello I'm trying all ways to make it work (I know this system works, 1 month ago i got it working without any driver, just plugging the USB on a computer, i don't know why it's not working on this one (or maybe something mysterious inside the audio system itself). Anyway, thank you guys for replying so fast, I installed this but nothing changed (and even rebooting). I'll keep trying switching plugs, testing and rebooting all the time...
