* The patch is based on Clemens Ladisch's patch to support the UR22 (http://linuxaudio.org/mailarchive/lad/2013/2/23/197831), with the device ID modified for the UR44. The patch was tested with kernel versions 3.12.11 and 3.12.12 and a PREEMPT RT-patched 3.12.12-rt kernel. Basic recording and playback appear to work. * NB: On one of the systems that I used to test the patch, I was never able to achieve xrun-free JACK performance at -p256 -n3 as I would invariably see xruns roughly once every minute. But this is a new box (Intel haswell NUC) and it seems there are many possible sources of the unacceptable latency. On an older i3 box, the performance was much better.
