udev regras para adicionar joystick para arm linux?

Question

Eu estou tentando adicionar um ambiente ID_INPUT_JOYSTICK = 1 ao udev quando um joystick é adicionado ao meu sistema. Isso não é necessário para desktop Ubuntu porque a propriedade já está lá, mas em uma versão linux estou usando ele não mostra. O sistema de destino é uma versão do braço do linux. Então, a execução das informações do udevadm mostra:

looking at device '/devices/platform/xhci-hcd.1/usb3/3-1/3-1:1.0/input/input6/event6':
    KERNEL=="event6"

    ATTRS{bDeviceProtocol}=="00"
    ATTRS{devpath}=="1"
    ATTRS{idVendor}=="046d"
    ATTRS{speed}=="1.5"
    ATTRS{bNumInterfaces}==" 1"
    ATTRS{bConfigurationValue}=="1"
    ATTRS{bMaxPacketSize0}=="8"
    ATTRS{busnum}=="3"

    ATTRS{version}==" 1.10"
    ATTRS{urbnum}=="16"
    ATTRS{ltm_capable}=="no"
    ATTRS{manufacturer}=="Logitech"
    ATTRS{removable}=="unknown"
    ATTRS{idProduct}=="c218"
    ATTRS{bDeviceClass}=="00"

Mas eu quero que eu veja um ENV {ID_INPUT_JOYSTICK}="1" adicionado ao final, algo como:

looking at device '/devices/platform/xhci-hcd.1/usb3/3-1/3-1:1.0/input/input6/event6':
    KERNEL=="event6"
    SUBSYSTEM=="input"
    DRIVER==""
  looking at parent device '/devices/platform/xhci-hcd.1/usb3/3-1/3-1:1.0/input/input6':
    KERNELS=="input6"
    SUBSYSTEMS=="input"
    DRIVERS==""
    ATTRS{name}=="Logitech Logitech RumblePad 2 USB"
    ATTRS{phys}=="usb-xhci-hcd.1-1/input0"
    ATTRS{uniq}==""
    ATTRS{properties}=="0"
    ENV{ID_INPUT_JOYSTICK}="1"
    ..

As regras que adicionei são estas: /etc/udev/rules.d/91-joystick-rules

SUBSYSTEMS=="input", ATTRS{name}=="Logitech Logitech RumblePad 2 USB", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1"

Além disso, o /lib/udev/rules.d/ difere do desktop ubuntu:

Eu tentei reinicializar meu sistema e brincar com as regras específicas, mas não consigo entender por que meu ambiente adicionado não está sendo exibido. Qualquer ajuda é apreciada.
