There is no support in Linux for this hardware. From the computer's |
24 |
POV it's just an external USB device, partially an audio device, and |
25 |
partially just controlled over USB. I've told pulseaudio and KDE in |
26 |
general not to use it but I continue to see problems. I have no idea |
27 |
what functionality the USB control port is providing. |
28 |
|
29 |
I think the next step is to actually blacklist the device by its |
30 |
USB device ID ala something like this: |

33 |
|

and see what happens. |

|
36 |
This whole thing isn't overly critical to me. The device itself is |
37 |
stand alone in operation. It's only attached to a computer to do editing |
38 |
which actually can be done on the device's GUI without a computer, or |
39 |
I can hook it to a Windows laptop, or even this machine if booted into |
40 |
Windows. I was just wanting to be in Linux but open a VM to allow |
41 |
me to edit more easily, which I actually can do but I have to hit the |
42 |
reconnect button in software or pull the USB cable, both of which |
43 |
work but are hacks. |
