There is a "driver" which I long wanted to be in official alsa: line6usb. http://www.tanzband-scream.at/line6/

While the code exists, I looked at it and in my opinion it's not ready for inclusion in alsa. For example, there is some MIDI code which belongs to userspace but it's in the kernel module.

I have already contacted the maintainer of the project, so we can make this happen. My question are: - what "communication" steps do we need to put this code here? - do we have to put the initial line6usb support in one single patch or a step by step is preferred? - once the code is here, how can we improve it or make changes? - any other trap we could avoid right now? any suggestion of how can we make this the smoothest way possible?

Thanks a lot!
