--- Comment #1 from Michał Pecio (michal.pecio@gmail.com) ---
Is this lspci output from the working 6.11 system?

On 6.12 you should see
        Kernel driver in use: xhci-pci-renesas
        Kernel modules: xhci_pci, xhci_pci_renesas

and you need CONFIG_USB_XHCI_PCI_RENESAS to have this module if you are
building your own kernel, see commit 25f51b76f90f.

CONFIG_USB_XHCI_PCI_RENESAS and loading this module make it work. This option
and module weren't required in 5.x.
