Has anyone tried the Belkin F5U623 card? This is plain PCI, which is exactly what I am looking for as I have no available PCIe slots left. But I do not know what chip drives this Belkin card, so I do not know if it works under OS X.
I already own a Texas Instruments TSB82AA2 (sometimes also referred to as SN082AA2) based PCI card, and I can confirm that OS X does not detect it as an available Firewire controller. I also own a PCIe x1 card, based on a Texas Instruments XI02213 chip, and this is nicely detected by OS X (e.g. macOS Sierra).
If you have experience with the Belkin F5U623, please say so!
Alternatively, if you know of any plain PCI based IEEE 1394B controller card, let me know!
