The Alesis people informed me that currently all their resources are devoted to getting their devices running on Windows/Mac, and that they are currently not able to free up resources for us. They will contact us when they are ready to support us.
If you are interested in getting an Alesis device and using it on Linux, please query the Alesis sales support to see what the status on this is. (Such that at least they know that interested people exist)

Fourer Dominique reports via ffado-devel that this device works for him, at least in so far as audio in/out is concerned.
