針對q101行動網卡寫udev rule，但無法作用

[ronmi]

用udevadm把debug選項打開之後，發現rule完全沒有被執行
用udevadm test add來看，rule會被讀到；但順序我試過30(最優先)和90(幾乎是最後)兩種，也都無效
我猜是不是哪裡語法有寫錯，可是從man和google來看，似乎都是正確的

使用的是ubuntu 9.10/udev 147~-6.1/libudev0 147~-6.1/kernel 2.6.31-14
附上rule和udevadm查到的資料

rule有試過兩種寫法

原來是我被騙了，要用udevadm control --reload-rules才會真的重讀rules
重讀後會執行到了

不過原本的rule無法作用，原因可能是裝置還沒有完全初始化，就被suspend，導致後續動作也無法完成，稍微修改後已可正常使用

附上正常版的udev rule，把他丟到/etc/udev/rules.d裡，給他60以下的順序就好了(我是用30-q101.rules，在ubuntu裡這是最高優先了)
