I am having trouble with my pci firewire card in Ubuntu 14.04 LTS. It previously worked fine but has been unused for a while and no longer works. The card shows up in lspci:
00:00.0 FireWire (IEEE 1394): VIA Technologies, Inc. VT6315 Series Firewire Controller (rev 01)
Subsystem: VIA Technologies, Inc. VT6315 Series Firewire Controller
Kernel driver in use: firewire_ohci
However, I do not get fw0 and fw1 in /dev as before, so I cannot use the card. How do I go about troubleshooting this?
