Linux white-un 3.13.5-1-ARCH #1 SMP PREEMPT Sun Feb 23 00:25:24 CET 2014 x86_64 GNU/Linux

I have a similar problem with my Focusrite Scarlett 8i6. The kernel under which I've noticed the xhci errors is 3.14.3-rt4 #1 SMP PREEMPT RT x86_64, which I built myself; however I have seen the same behavior (jackdmp not starting or stopping properly) when running other kernels including Ubuntu's 3.13.0-27-lowlatency and it's likely that the underlying cause is the same.

It looks like a problem in the XHCI driver. A patch was posted to the linux-usb mailing list a couple of years ago. It's fixed in mainline, but I'm still seeing it with the Ubuntu LTS kernel (3.13.0-64). http://marc.info/?l=linux-usb&m=136944610123146&w=2
