If the USB keyboard and/or mouse are on the same bus as the soundcard x-runs might occur whenever you move the mouse or type something (just guessing here though). You might want to try to put the UA-25EX on a different bus than the USB keyboard and mouse. In your case the sound device sits on its own on bus 004, maybe the situation is different in your friend's case.
