udev 规则自动执行脚本

我想创建一个 udev 规则，在耳机插入时执行。因此我遵循这教程，但我的规则似乎不起作用。

输出

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

插入耳机后是：

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

我选择了/dev/hidraw4，当我输入

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

我得到以下输出：

*我为我的 udev 规则选择了带星号的值。
我的完整规则是：

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"

如果输入到终端中，这两个脚本都可以工作，因此错误一定出在 udev 规则的某个地方！
