Hi James,
I expected the focusrite Saffire 6 to work but it is not recognised by the

system or Jack. Then I read this
http://ubuntuforums.org/showthread.php?t=1486482&page=3  from last year.

Maybe I'm doing something wrong but it would appear that there is no easy

solution.
Would usb 1 be fast enough for live processing?
What latency do you get with 2i4 (USB2) looks good.
Ralf, thanks for your calculations.
Cheers,
Saul

I guess I understand now:
512 samples / 44.1 kHz =3D 11.609977324 ms
11.609977324 * 2 =3D 23.219954649 ms ~ 23.2 ms
Yes, this is audible.
