    2 PCI cards with same signature


    Hi

    I have PCI card with driver.

    Now I have to drive 2 PCI cards having identical device ID, vendor ID,subvendor ID, subdevice ID and also class.

    How to modify the driver code to drive two PCI cards with identical device ID.

    Can any body suggest me hint please.

    Thanking you.

    I'm not vey familiar with PCI, but it should work in the same way as with USB where you also can connect dozens of identical devices with the same IDs.

    If you launch a "/sbin/lspci", there a some numbers on the left. They should be some specifiers for your PCI system and you will prabably talk to your devices using those numbers.

    "cat /proc/bus/pci/devices" gives also lots of numbers, some of them presumably for the same purpose.
    Bus Error: Passengers dumped. Hech gap yo'q.
