The way ffado works, these will all be joined (possibly automatically) in one
big device. and each channel on each device is named unique(?) and aliased
with system_*. So it should be the same ports in jack everytime you start the
setup.

But I don't think ffado is currently able to do dynamic add/remove. Can't test
it here, not enough fw-devices. ;-)

For the real problem: Maybe udev can show some more information (like serial
number) for the pci devices? Or maybe it can provide the interrupt. That way
unique devices would be possible.
