According to the logs the device seems to work...

If you upload the firmware using another OS, the old freebob driver 
should also work (and more reliable than FFADO).

However you should always run jack in realtime mode using the -R flag:
jackd -R -d freebob
or
jackd -R -d firewire

There should be plenty of info on the web regarding getting jack to work 
in realtime mode. Also in our list archives btw. Try the freebob site.
Non-realtime mode won't work. Especially not for FFADO. Running 
jack+ffado in non-RT mode causes the behavior you are experiencing.

Some notes:
- everytime jack crashes you should issue a bus reset, e.g. by 
unplugging and replugging the device. After a jack crash you can't just 
restart jack since the device is in a bogus state.
- running jack in RT mode is essential
- once the firmware is uploaded, you can use freebob, so please do if 
you want to actually use the device. FFADO is very experimental.
- downloading the firmware from the other OS is more reliable than using 
our current tools.

Greets,
