i recollected ideas once again and i've found all the errors i did,
excuse me because you have explained to me many and many times and i've
never understood, basically i tougth that nrpacks was optional for
lowlatency, and frankly for now i want only to use this card, i'll see
for lowlatency after i have a constant sound out of this, even with
100ms latency; then, i found (you were right) a couple of files from
preivous compiling of jack, i removed, recompiled and it gone ok, then i
missed that you merged the jack usx2y driver with alsa's one, so i
retried to recompile everything, new alsa (1.0.8), new jack (0.99.48)
and i've been able to run jack, the card is recognized, but still it
have troubles..

Sorry. The audio interface "hw:0,2" doesn't support any of the hardware
sample formats that JACK's alsa-driver can use.
ALSA: cannot configure capture channel
i've tried with plug layer (-d plughw:0,2) and it worked, i get some
xruns, but the audio is a loud continous noise.
Be advised however, that you get far better results if
you're running
jackd in realtime mode (-R) *and* under the help of a RT capable kernel,
like 2.6.10-mm1 with Ingo's V0.7.34-01 realtime-preempt patch.
unfortunately i cant compile realtime preempt patches, i've tried almost
any version but they seems to be linux/x86 only. i keep searching some
kind of lowlatency patches that i can apply succesfully
If you really want to work on your us122, seriously, I
guess there's no
better way to get around it. IMHO.
unfortunately i know
Bye now.
bye, and excuse me
