I have an HP734n that had the on-board sound decide to stop working. No
problem right? I purchased a Creative PCI Sound card to replace the on-board,
plugged it into my open pci slot, installed the software and thought I was a
computer genius. Until I tried to use my scanner plugged into the USB. Then
I realized that anything plugged into the USB when the sound card is in the
pci slot will not work. Creative told me to assign the sound card to a IRQ 5
setting. It is currently set to IRQ 17, the USB ports are all set to IRQ 21.

How do you change the IRQ settings? I have Windows XP Home Edition and SP2
installed. Every time I have gone through the control panel to the system to
the properties to see if I could change IRQ settings and they are all grayed
out (I can't currently adjust anything).

Help, I need to use the scanner and have the sound for learning about some
graphic programs.

The SB Live! card takes two interrupt requests (IRQ's), one is IRQ5 which
defaults to the SB 16 emulation and the other is of the higher range 9,10 or
11 for the SB Live! entry under Sound, Video and Game controllers in the
Device Manager. If a motherboard does not have ISA slots, the BIOS assigns
all IRQs to PCI. Therefore, you need to change the BIOS setting in order to
assign an ISA IRQ to the card's SB16 Emulation. It is recommended to reserve
IRQ 5 for legacy device in your BIOS settings.
