VFIO_DEVICE_SET_IRQS failure: Device or resource busy

[NezumiRyu]

Hi!

I try to passthrough Iphone to MacOS VM, but I have no luck.
After some tests, I read that it could be easier to passthrough whole PCI card than single Iphone.
So I bought PCI USB card, and I try to forward it.
Unfortunately when I add whole 0000:37:09, then I have an error:

kvm: -device vfio-pci,host=0000:37:09.1,id=hostpci0.1,bus=pci.0,addr=0x10.1: vfio 0000:37:09.1: Failed to set up TRIGGER eventfd signaling for interrupt INTX-0: VFIO_DEVICE_SET_IRQS failure: Device or resource busy

I will be grateful for any ideas.
