      Description of problem:

      Reference doc https://docs.redhat.com/en/documentation/openshift_container_platform/4.20/html-single/virtualization/index#virt-enabling-usb-host-passthrough_virt-configuring-usb-host-passthrough

      Step 3 in doc is asking to add usbHostDevices as "kubevirt.kubevirt.io/jsonpatch", but it is supported to add it in hco spec directly like below, and we don't have to go through unsupported jsonpatch:

      oc patch hyperconverged kubevirt-hyperconverged \
  -n openshift-cnv \
  --type=merge \
  -p '{
    "spec": {
      "permittedHostDevices": {
        "usbHostDevices": [
          {
            "resourceName": "kubevirt.io/peripherals",
            "selectors": [
              {"vendor": "045e", "product": "07a5"}
            ]
          }
        ]
      }
    }
  }'

      Reference doc https://docs.redhat.com/en/documentation/openshift_container_platform/4.18/html-single/virtualization/index#virt-configuring-vm-use-usb-device_virt-configuring-usb-host-passthrough

      Step [2] is asking to edit VMI spec, but we have to add the device in the VM spec like below:

       % oc get vm rhel9-kvm -o yaml |yq '.spec.template.spec.domain.devices'
hostDevices:
  - deviceName: kubevirt.io/peripherals
    name: test-usb
