MOTU 828 MKii

Sun Sep 6 16:23:46 BST 2009

HI all!,

 I've readed  in the web of ffado that MOTU has not proved to be competent to programming
 drivers for 828 mkii firewire for linux, however somebody have obtained the way to work it with high latencies.
Has anybody connected a MOTU 828 MKii Firewire to ubuntu studio with RT kernel and has verified that works?
anybody knows the way?

Im trying it and jackd recognice the in/outs but give me an "stream buffer error".
