I add to this.
Just some minimum interface to communicate with the device would be great. I'm running the audiofuse control center on a windows vm and its ok. But i can't use the interface on linux as it does not remembers / persists the spdif config (and the device should be disconnected from windows vm, to be used on linux host).
I'm a developer and i'm good on putting hands dirty over any issue / technology.
You could even give some access details / specs if it does not comprimises your confidential information and i could choose a library, language and/or technology to try to communicate with it.
Or well, doing something basic your side so we have basic support would be great.
