Was really upset. I tried freebob + jackd from freebob.sf.net. libavc from svn, libiec61883 1.0, libraw1394 1.2 cmdline: jackd -d iec61883 -o osc.udp://localhost:31000 FreeBoB wiki's list of working setups contains FA-101 + gentoo (my distro). When run in the first time, jackd starts, but there's no sound, and seems processing callbacks aren't called (no interrupts?). Dmitry.
