Hi Peter,

I don't know about wine, but the main issue is that if the device is
used by ALSA (kernel driver), you cannot at the same time access it from
a user-space application (maybe try unloading the ALSA snd-usb module,
but I would not get my hopes up).

The first generation of scarlett-devices is supported by the
Linux-kernel. Since Linux 3.19 there is a dedicated driver to expose the
complete mixer interface and there are also some UIs.

At some point Focusrite changed the USB-IDs, and perhaps also the
protocol. As far as I know, nobody has yet investigated or reverse
engineered those.

Cheers!
