[FFADO-user] tc electronic Impact twin

[Ion A. <nol...@gm...>]

Hi everyone, I've got a tc electronic impact twin that I'd like to use
on my Debian 6.0, linux 2.6.32-5-486, using libffado 2.0.1+svn1856-5,
and jack 1.9.6~dfsg.1-2. (all downloaded with apt-get).
I use a pci firewire card, to connect my TC electronic impact twin to
my computer, that seems to be recognized:
#lspci
02:09.0 FireWire (IEEE 1394): Texas Instruments TSB43AB23 IEEE-1394a-2000
Controller (PHY/Link).
Then, with the impact twin switched on, after observing that ardour did not
detect the card, I tried the following:
# jackd -R -d firewire
jackdmp 1.9.6

This seems to validate what is written in your supported device list
http://www.ffado.org/?q=devicesupport/list&page=3
Indeed, the impact twin is not there.

However, as some other TC electronic cards are supported by ffado, I'm
wondering whether
if with some more investigation (like downloading new versions of ffado
software, configuring
,etc) I could make the impact twin work, or whether the needed effort
consists in reverse engeneering this device and develop a new driver :)
Thanks in advance, and congratulations for all what you have already
achieved in this project !
