未触发删除设备的 UDev 规则

我有一个带有集成 USB 集线器（和物理电源开关）的显示器连接到我的 pi，并且想要在打开和关闭显示器时执行两个不同的脚本。

打开显示器的第一部分工作正常，但是当再次关闭显示器时，不会触发任何内容。根据其他论坛帖子，我尝试了该规则的不同变体，但没有成功。

规则文件/etc/udev/rules.d（包含所有三种变体）

SUBSYSTEM=="usb", ACTION=="add",    ATTR{idProduct}=="2514", ATTR{idVendor}=="03f0", RUN+="/home/pi/monitor_on.sh"
SUBSYSTEM=="usb", ACTION=="remove", ATTR{idProduct}=="2514", ATTR{idVendor}=="03f0", RUN+="/home/pi/monitor_off.sh"
SUBSYSTEM=="usb", ACTION=="remove", ENV{ID_MODEL}=="2514", ENV{ID_VENDOR}=="03f0", RUN+="/home/pi/monitor_off.sh"
SUBSYSTEM=="usb", ACTION=="remove", ENV{idProduct}=="2514", ENV{idVendor}=="03f0", RUN+="/home/pi/monitor_off.sh"

测试udevadm test告诉我，前两个删除规则应该触发，第三个则不会。

udevadm test --action="remove" /devices/platform/scb/fd500000.pcie/pci0000:00/0000:00:00.0/0000:01:00.0/usb1/1-1/1-1.4

然后关闭显示器，不会触发monitor_off.sh脚本。daemon.log有很多消息，不知道如何理解它们。以下是与 USB 集线器相关的内容（1-1.4）。

我还尝试使用与orATTRS相反的方式，这确实会触发脚本，但是它会根据连接到集线器的内容多次触发脚本。ATTRENV

操作系统版本是raspbian buster。
