Hi....Good Afternoon

i bought usb mass storage card from one company . the interface of my
usb mass storage card with motheboard is PCI. 

the Design is smthing like this......

pci-Pci Bridge --------------->pci/USB2 bridge ----------> usb2/NAND 

controller----------------->NAND CHIPS. 

the hardware manual of this card tells PCI Interrupt (INTB) is passed to
PCI Slot.

Now i wrote the pci Device Driver
rq-number.html>  to know the vendor id, device id ,int line, int pin
etc... i got the vendor id ,device id but on INT LINE i am getting 0XFF;
i am not able to undestand tht why i am not getting the exact IRQ for
this card...

is this is correct way what i am doing if not please suggest me how to
get the correct IRQ no....

thanks in advance
