How can I change IRQ address of USB port? Thanks.

[newbie]

My soundcard and one of my USB ports shares an IRQ address.
No matter what I try, I can't get either to change to an open address.

In either properties box, the IRQ addresses are not configurable.
Thanks for any help anyone can throw my way.

specs:
WindowsXP SP2
Soundblaster PCI 128

in most cases this is not a problem at all and is one of the benefits of
the PCI standard!! However, some PCI cards (and particularly older or
badly designed cards) or their drivers can have problems sharing IRQs
and in this case it is necessary to know on which slots this will occur.
If your PCI device is having a hard time sharing IRQ's, and it claims to
be PCI2.1 compliant, complain at the manufacturer to get the driver fixed!
Note you can force a particular IRQ number to be used by a particular
"INT Pin #" using the PNP/PCI Configurations Setup in the BIOS. This
allows you to force a certain slot to use a specific IRQ. You should not
normally need to do this.
