      Description

      There seems to be an issue with ACPI since Device->pnp.unique_id is always 0 so multiple devices with the same hardware_id won't get added in the drivers.

      Since Device->pnp.unique_id is 0 even the ACPI devices that get added will not work either
      as the path is not correct.

      In windows the devices are detected as PNP0501\1, PNP0501\2, PNP0501\3 ..

      Below is the log.
