No, this does not cause an xrun, because even though the USB interrupt

interrupt is #5 or #10 does not matter.
I get no xruns at 32 (!) frames using 2.6 with
the VP patches,
and my soundcard shares an interrupt with USB:
(Non-argumentive if it's unclear) Please stick a USB mouse on the USB
port that is shared and wiggle it madly while doing some of this. Can
you create an xrun?
BTW - PIC or APIC interrupts?
PIC (as in I only have irqs 0-15), but APIC works the same way.
