yessirree... the firewire port *does* work in the R400. I played with it 
for about a half an hour and there's possibilities there may be glitches 
that come up later, but so far, it seemed to work flawlessly.

Currently I'm running ffado 2.0.1-3.20100706.svn1864.fc12

Can you find out what chipset the firewire interface uses (i.e., is it 
Texas Instruments)?  Usually, from what I've read, the TI chipsets are 
the ones that seem to work best for linux audio. 



Thanks,

Len
