Is this occurring repeatedly? The `{781aee18-7733-4ce4-add0-91f41c67b592}` interface is `GUID_BLUETOOTHLE_DEVICE_INTERFACE` from !8174 which hasn't been merged. `3758096933` is `ERROR_NO_SUCH_DEVICE_INTERFACE`, so this likely happened because a Bluetooth device was initially discovered during enumeration by `DevGetObjects`, but disappeared soon afterwards. Is Bluetooth discovery turned on this system? I could add a check to `test_dev_object_iface_props` to skip the current device if `SetupDiOpenDeviceInterfaceW` fails with `ERROR_NO_SUCH_DEVICE_INTERFACE`, but it's also fair to assume that device interfaces wouldn't exist only for a few seconds...
Yes, this happens systematically. I don't think discovery is turned on.
