Unable to pass USB to QEMU machine

Hello, I have thinkpad P50 and I am trying to passthrough my USB controller to QEMu machine.
Error message: internal error: qemu unexpectedly closed the monitor: 2022-10-04T16:57:41.792764Z qemu-system-x86_64: -device {"driver":"vfio-pci","host":"0000:00:14>
                                         Please ensure all devices within the iommu_group are bound to their vfio bus driver.

This seems quite weird to me as I have USB controller passed through successfully

> lspci -nnk 8086:a12f

00:14.0 USB controller [0c03]: Intel Corporation 100 Series/C230 Series Chipset Family USB 3.0 xHCI Controller [8086:a12f] (rev 31)
        Subsystem: Lenovo Device [17aa:222e]
        Kernel driver in use: vfio-pci
        Kernel modules: xhci_pci

Any help would be greatly appreciated.
Thank you
