Mine is

06:07.0 FireWire (IEEE 1394): Texas Instruments TSB43AB23 IEEE-1394a-2000
Controller (PHY/Link)


It has always worked fine for me until this socket or cable fail.
Fortunately the mobo has two connectors and the full-size one still
worked.  But for testing I got this PCI-E card on Amazon
<https://www.amazon.com/dp/B07F67WJ9S> for $14.  It's got a VIA VT6306/7/8
chipset.  It connected to the STB fine as well.
