Hi @Elias64Fr,Hi @CaseySJ
Note that I have exact similar Ioreg with not patched firmware. Note also that class-code is different and same as thunderbolt 3 (0x88000).
On thunderbolt 4, we have controller detect as something different device.
You could try on PCH port (RPxx). Some motherboad specify some thunderbolt compatible port on their user manual. @caley13 have his board on PCH port.
On Designare Z390 this card was installed in RP21 (PCH-lane slot), but Linux encountered the same problem where
/sys/bus/thunderbolt
directory did not materialize. I then moved it to Asus Z690 (CPU-lane slot), where Linux encountered the same problem.I’ll try a couple more experiments before giving up. Fortunately the card was not expensive.
But more importantly, because we found a very good solution for Thunderbolt Local Node on Asus 500, 600, and 700 series boards, I am very happy!
