Due to lack of bandwith with my internal USB bus,
like
we are discussing in another thread, I ordered a Trust
SuperSpeed 2 Port USB 3.0 Laptop Express Card.

I have a new USB bus, and my Edirol UA25-EX is the
only device working in bus #3

I have my device working on IRQ 16.
everything seems all right, so I start JACK, and I
have this error.

I suppose that the problem is not JACK related, is
ALSA related:
