I try to start jack with command "jackd -R -d firewire". The light of my FP10 changes from red to blue. After few seconds it changes to red again and ffado says "Cannot start streaming threads: -1" and jackd exits.
This happens always when I try to start jack using ffado backend. Bus reset doesn't help.
This problem came after I changed my firewire controller. Gscanbus can see that FP10 is plugged.
