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 <http://www.linuxforums.org/forum/linux-kernel/157955-help-finding-pci-i 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 Regards sandeep Gulati | HAL-Edgewood [email protected] +919620291990
