Interesting that 2.0 vs 3.0 port matters for you, I don't think it did to me. > This can be worked around using using..?

Nobody has written an ACPI attachment for the genet driver yet :( (And for other Pi-specific things for that matter. Meanwhile in NetBSD: https://dmesgd.nycbug.org/index.cgi?do=view&id=5562 'bcmmbox0 at acpi0 (RPIQ, BCM2849-0)' and so on) I wanted to do the genet one but kinda don't have the time/motivation right now. > * pciconf -l yields no PCI devices and dmesg suggests no pci bus was > detected (grepping for pci yields no results) What do you want to do with PCI? Your USB works, forget about PCI. (The ACPI DSDT table presents the XHCI controller that's behind PCIe *as if* it was not behind anything, just directly attached onto the SoC. No PCI support needed at all!) (Yes, this does mean that RPi4-UEFI is not compatible with desoldering the XHCI controller chip and adding a PCIe riser there, lol.)
