觸發特定鍵盤的udev規則

我需要爲特定的鍵盤編寫一個udev規則，該規則似乎沒有任何與之匹配的唯一屬性。觸發特定鍵盤的udev規則

下面的行是插入設備後的輸出udevadm monitor。有什麼我可以用來唯一識別這個鍵盤嗎？

下面是堵塞鍵盤到不同的USB端口線。據我所知，似乎沒有任何信息保持不變。

編輯：使用-v的lsusb，我能找到idVendor和idProduct。

所以我創建了以下udev規則：

SUBSYSTEM=="usb", ATTR{idVendor}=="0x04b3", ATTRS{idProduct}=="0x3025", RUN+="/home/myuser/bin/udev_jap.sh"

然而，沒有什麼是迄今爲止觸發。奇怪的是，idVendor和idProduct信息沒有顯示在udevadm monitor上。這是否意味着udev無法匹配這些屬性？

這是一個老問題了，反正：

您必須刪除0x十六進制的前綴。
請注意，ATTR和ATTRS是不同的，但你的情況都應該工作。
您的腳本udev_jap.sh應家當#!/bin/sh啓動或運行shell本身：
```
RUN+="/bin/sh /home/myuser/bin/udev_jap.sh" 
```

試試這個：

SUBSYSTEM=="usb", ATTR{idVendor}=="04b3", ATTR{idProduct}=="3025", RUN+="/home/myuser/bin/udev_jap.sh"
