@damjank any update on this? I’m running into the same issue with an Ubuntu VM (also running XOA from source files).
I am moving my virtualization server to a new Supermicro X11SDV-4C-TP8F motherboard where I have Home Assistant virtualized with XCP-ng/Xen Orchestra. I have a separate PCI USB card based on a Renesas controller passed through to the VM for a USB Z-Wave controller for use with HA. The VM boots up without any error but I am receiving xhci_hcd errors on the main HA CLI screen (here). On my older Supermicro X10SLL-F MOBO this worked perfectly fine so not sure what's preventing me from doing it on this board. I've had issues in the past with IOMMU/RMRR but don't think that is the problem now since the VM boots up just fine. Any help would be greatly appreciated!
