There is no support in Linux for this hardware. From the computer's POV it's just an external USB device, partially an audio device, and partially just controlled over USB. I've told pulseaudio and KDE in general not to use it but I continue to see problems. I have no idea what functionality the USB control port is providing. I think the next step is to actually blacklist the device by its USB device ID ala something like this: https://www.projectgus.com/2014/09/blacklisting-a-single-usb-device-from-linux/ and see what happens. This whole thing isn't overly critical to me. The device itself is stand alone in operation. It's only attached to a computer to do editing which actually can be done on the device's GUI without a computer, or I can hook it to a Windows laptop, or even this machine if booted into Windows. I was just wanting to be in Linux but open a VM to allow me to edit more easily, which I actually can do but I have to hit the reconnect button in software or pull the USB cable, both of which work but are hacks.
