It, ALSA firewire-tascam driver, works for systems in which Linux kernel 
is used. It's already included in Linux kernel source since kernel v4.4.

As of kernel v4.19, it supports below functionalities:
  - data transmission for PCM frames via ALSA PCM interface
  - data transmission for MIDI messages via ALSA rawmidi interface

Recently I got Scott's help and work to support handling control 
messages from faders/knobs/buttons on control surface of FW-1884/FW-1082. You can 
see recent patches in my remote repository:

Apparently, no. It comes from my work for reverse engineering, by sniffing 
packet communications over IEEE 1394 bus.

I have no such chance, as well as the others.
