上當了，買了個華為et302，ubuntu10.10卻不支持！

[qinmianshou]

我有張廣東移動的無限流量卡，以前是用WM手機拖本本上網的，現在手機要裝湖南本地卡，想買個無線網卡插本本，網上搜索時看到幾篇博文都說ubuntu10.10完美支持et302，於是信到十足，馬上下單，結果貨到了插上一試，按指示燈看確實已經註冊到EDG網路了，但是沒有連線，電腦多出一個cmcc sd裝置，然後我就不懂了，怎麼辦？

cmcc-sd是中国移动的无线啊，说明识别出来了啊，怎么了？

根据提示一步步走，最后点击连接..

google搜索發現usb-modeswitch-data(20111023-1)版本裏邊添加了ET302的信息，而程式庫裏還是老版本（20100826-1)，不知道有沒有關係？

另外，中英文論壇都有人提到ET302用的是什麼CDC驅動，好像無解了，操！
