Description and Notes

This firewire card uses the firewire_ohci kernel module:

$ lspci -vvv
01:00.0 FireWire (IEEE 1394): VIA Technologies, Inc. VT6315 Series Firewire Controller (rev 01) (prog-if 10 [OHCI])
  Subsystem: Bitland(ShenZhen) Information Technology Co., Ltd. VT6315 Series Firewire Controller
  Device tree node: /sys/firmware/devicetree/base/scb/pcie@7d500000/pci@0,0/usb@0,0
  Flags: fast devsel, IRQ 67
  Memory at 600000000 (64-bit, non-prefetchable) [size=2K]
  I/O ports at <unassigned> [disabled]
  Capabilities: [50] Power Management version 3
  Capabilities: [80] MSI: Enable- Count=1/1 Maskable+ 64bit+
  Capabilities: [98] Express Endpoint, MSI 00
  Capabilities: [100] Advanced Error Reporting
  Capabilities: [130] Device Serial Number 00-11-06-ff-ff-00-87-fb
  Kernel modules: firewire_ohci

However, when the Pi boots, it seems the driver can’t properly initialize the card:

$ dmesg
[    6.125780] firewire_ohci 0000:01:00.0: enabling device (0000 -> 0002)
[    6.125923] firewire_ohci: probe of 0000:01:00.0 failed with error -12
