I'm using a M-Audio Transit USB audio interface with a laptop and I
was wondering if the rtirq script is actually setting the right
priority for it. Would booting the laptop with the interface connected
or disconnected make a diference? Is there something that I should
tweak in the script to make it favor the USB port? Also I noticed that
using the stock Fedora kernel I get much better performance than with
the RT kernel, so that's why I was wondering about the priorities.

Also, is there any recommendation regarding buffer sizes in Jack for
using USB interfaces? I remember reading somewhere that the periods
should be 3, is this true?
