Thank you, unfortunately there are no `alias` entries or any other entries that contain the ID that I dynamically added for the driver I'm looking at (vfio-pci). Maybe this approach only works for the IDs the driver has by default, not the ones added dynamically via `new_id`? Only for other drivers like `amdgpu` that have default IDs, I can see the aliases.
