Though the bad controller card and the good onboard controller apparently sit both behind the same bridge, which would be 00:1e.0 PCI bridge [0604]: Intel Corporation 82801 PCI Bridge [8086:244e] (rev a5) according to the posting on October 12, so the bridge works at least for the onboard controller. > pull it out, run lspci >lspci.1.txt > add it back, lspci >lspci.2.txt > > diff lspci.1.txt lspci.2.txt > > If you don't see a new entry... um... you don't have a card ;) > > if you do see a 2nd firewire card, you should see > /dev/fw0 > /dev/fw1 > > and when you plug in your dv camera to either card: > /dev/fw2 > > > > > > I can't find any way to turn off the on-board firewire to try this.
