新装ubbuntu9.04,现在不能识别huawei ec226

[billybigstick]

插上huawei ec226后，系统没有任何反应，Network Connections里的Mobile Boadband下Aoto Mobile Broadband (CDMA) connection总是连不上。
参考并实施了如下数帖之建议和帮助后，依然毫无反应

现在terminal下
sudo wvdial
--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATX0
OK
--> Modem initialized.
--> Sending: ATM1L3DT#777
--> Waiting for carrier.
NO CARRIER
--> No Carrier! Trying again.
--> Maximum Attempts Exceeded..Aborting!!

是不是因为驱动问题，ec226一直未被识别运行啊？需要装那个usb_modeswitch-1.0.2么？
谢谢朋友们帮忙！呵呵
