Hi there!
I own a Tapco Link.Firewire which I dearly want to use. However, due to issues with my graphics card or drivers under Windows, I'm unable to use it on Windows. So I'm trying to run it with FFADO on Linux. Obviously, default configurations won't do, since FFADO does not seem to support it (yet).
Adi in #ffado @ freenode.net told me that Tapco Link.Firewire might be an AVC device. I couldn't retrieve any information on the chipset it is using on the Internet, so I dl'd the 1.999.42 tarball (I have the exact same compiled libffado/etc. installed from the official Ubuntu repositories), changed the rw access for my user onto /dev/raw1394 and tried to run ffado-test.
That's what I got: http://paste.ubuntuusers.de/396392/
Any further step I should be taking to obtain information? I'd be glad if I can help :)
