当我使用12.04将3G USB调制解调器连接到笔记本电脑时,Network-Manager中没有任何显示。该调制解调器在11.10中工作,并且调制解调器在Network-Manager中显示,但在12.04中却没有显示!
下面是的输出lsusb
和usb-devices
上两台机器,一个具有11.10和其他与12.04:
Ubuntu-11.10:

Ubuntu-12.04:
$ lsusb

$ usb-devices

如上述命令的输出所示,该设备在11.10中被检测为调制解调器,但在12.04中被检测为USB存储设备(该设备既是3G调制解调器又是SD卡USB适配器)。
有帮助吗?
System -> Preferences -> Network Connections -> Mobile Boradband
吗?
