我有一个 BSNL EVDO 调制解调器，它在 ubuntu 10.10、11.04 和 11.10 上运行良好。昨天通过更新管理器升级到 12.04 后，它无法工作，甚至在网络管理器上也检测不到。我下载了 ISO（64 位），并在格式化分区后尝试全新安装，但没有任何效果。
我很惊讶更新破坏了它，请帮忙！！！
PS:: 经过测试，确保它在 Windows 上仍能正常工作

Ctrl从应用程序 -> 附件 ( + Alt+ )打开终端T。然后输入：
gksudo gedit /etc/modules
笔记：它会要求输入 SUDO Passwrod，请输入您的管理员帐户密码。命令提示符不会显示您的密码，只需输入密码并按回车键即可。
在文件底部，添加两行新代码，如下所示：
usbserial
option
然后关闭编辑器程序并保存。重启电脑，希望从现在开始一切正常！
