I pushed 'fireworks3-quirk' branch to my repository. It's nice to test
with your models if you have a enough time.
https://github.com/takaswie/snd-firewire-improve/tree/fireworks3-quirk

In this repository, another developing line is running (amdtp-variants).
I have a plan to post a part of them in this kernel developing cycle.
