Don't apologize, bugs happens. 

I thank you very much for this fast answer.

OK.

What I can say is that with kernel 4.13 under Ubunto Disco everything
was fine :-(

I can say too I never had to plug external power, the power by the
firewire cable has allways been enough for it. And this is still
working on Windows 10 (I have dualboot on my computer, but only do
audio things on linux, mostly with Ardour).

Thanks to you !!

I'll be waiting for your tests. Be sure to ping my anytime you need
info, log files or whatever. 

I'm "jpa" on irc.freenode.net, connected worktime (~9am ~8pm UTC+1)

Cheers,
