Hi,


US-428 ticks again here with attached patch applied on top of github's
jack2 master branch.

Rename linux/alsa/usx2y.c to linux/alsa/usx2y.cpp before applying the patch.

Preconditions outside of jackd:
-1: RT-Kernel running.
0: Connect to a real uhci, no hub nor ehci.
   That excludes most modern mainboards.
1: modprobe snd-usb-usx2y nrpacks=1
2: Make the uhci's irq priority high, like so:
   chrt -fp 90 `ps --ppid 2 -o pid,rtprio,cmd|grep irq/21-u|awk '{print $1}'`

Jackd invocation, mind the ,2:
       jackd -P78 -dalsa -dhw:1,2 -r44100


Regards,
Karsten
