    Haswell NUC CIR receiver (ACPI issue?)

    lmyllari

      The D54250WYK infrared receiver is not working out of the box in Linux. I have been testing this in 64bit Ubuntu 13.10 and OpenELEC 3.2.3.

       

      The following lines can be found in dmesg:

      [0.168692] pnp 00:08: Plug and Play ACPI device, IDs NTN0530 (disabled)
      [2.497482] nuvoton-cir 00:08: IR PNP Port not valid!

       

      Unloading the nuvoton-cir module, enabling the device resources and loading the nuvoton-cir module again seems to fix the issue.

      $ sudo modprobe -r nuvoton-cir && echo "auto" | sudo tee /sys/bus/acpi/devices/NTN0530\:00/physical_node/resources && sudo modprobe nuvoton-cir

       

      I dumped the DSDT and found this:

                      Device (CIRP)
                      {
                          Name (_HID, EisaId ("NTN0530"))
                          Method (_STA, 0, NotSerialized)
                          {
                              Return (IRST (0x06))
                          }
      

       

      Is this correct? If I'm reading this right, it claims the device is not present, is enabled, should be shown in user interface and is not functioning properly.
