I just got a Studio 192 USB3.0 device, and am going through the setup. I've installed Studio One 3.5.6.46910.
When Studio One starts up, I get the red skull and crossbones error alongside "Failed to open Line (presonus studio 192)".
When I configure audio devices, the dropdown list only shows "Windows Audio", and "No Audio Device".
However, I do see the studio 192 in the Windows audio device setup, and the "Line Presonus Studio 192" is selected as my default capture device.
