To Anyone with USB Add on PCI cards

Anyone use PCI USB add on cards? How many IRQs are they using?
- I have an Asus USB2.0 PCI card with 4 USB ports on a Asus server board that doesn't have on board USB (Athlon MPX Chipset issue), and I put it in and the BIOS sees Serial Bus Controllers on IRQ 10,11,12 (no OS is installed yet). Is this normal? I'm thinking of popping it out in case of potential conflicts with the NIC, RAID, and AGP card which use the same IRQs. And the legacy serial ports should be IRQ 3 and 4, as per the BIOS settings.
