udev regra para executar automaticamente o script

2

Eu quero criar uma regra do udev para executar quando meu fone de ouvido é plugado. Portanto, eu segui este Tutorial, mas minha regra parece não funcionar.

A saída de

udevadm monitor --environment | fgrep 'DEVNAME=/dev'

depois de conectar o fone de ouvido é:

DEVNAME=/dev/bus/usb/001/023  
DEVNAME=/dev/snd/controlC2  
DEVNAME=/dev/snd/pcmC2D0p  
DEVNAME=/dev/snd/pcmC2D0c  
DEVNAME=/dev/input/event19  
DEVNAME=/dev/hidraw4  
DEVNAME=/dev/bus/usb/001/023  
DEVNAME=/dev/snd/pcmC2D0p  
DEVNAME=/dev/hidraw4  
DEVNAME=/dev/snd/pcmC2D0c  
DEVNAME=/dev/input/event19  
DEVNAME=/dev/snd/controlC2

Eu escolhi / dev / hidraw4 e quando eu entro neste

udevadm info --attribute-walk --name /dev/hidraw4

Eu recebo a seguinte saída:

Eu escolhi os valores com um asterisco * para minha regra do udev.
Minha regra completa é:

KERNEL=="hidraw4", SUBSYSTEM=="hidraw", SUBSYSTEMS=="usb", ATTRS{manufacturer}=="Logitech", ATTRS{product}=="Logitech USB Headset", ACTION=="add", RUN+="/usr/local/bin/run-script-in-background.sh /usr/local/bin/usb-headset-set-default.sh"  

Os scripts funcionam se forem digitados em um terminal, então a falha deve estar em algum lugar na regra do udev!
