I’m trying to disable a IOMMU group because it’s the dreaded Asmedia controller for USB. I’m trying to use ra1nstorm for running a mac OS Mojave VM through Qemu to pass through and I need to disable it to get the VM running. This is what my IOMMU groups look like:

Why I’m asking this is because of this error:
Summary
(qemu) qemu-system-x86_64: vfio_err_notifier_handler(0000:04:00.0) Unrecoverable error detected. Please collect any data possible and then kill the guest
and also based off of other forums. Basically, I’m wondering if there’s a way to disable them with a script or something of that nature.
Thanks for your time.
