我在 Ubuntu 16.04 中安装 USB 调制解调器时遇到了困难。大多数情况下，我连接 USB 宽带调制解调器时，它都是以 CD-ROM 的形式连接的。
我从网上了解到，usb-modeswitch可以使用它将其切换到 USB 设备，但无法切换。网络管理器中甚至没有显示“启用移动宽带”选项（可能是因为它没有被检测为调制解调器）。
我尝试解决此问题的方法没有运气：

sakis3g后连接到调制解调器但没有成功，出现错误。降级
usb-modemswitch至usb-modeswitch-data14.04 版本，因为我的调制解调器在该版本下运行。

我遇到了同样的问题，我已经解决了。您需要为 Ubuntu 安装华为驱动程序。
1）配置lsusb在终端中 的结果（12d1:15d2例如，我的华为的 pid 是）参见ubuntuforums.org 上的帖子
2）下载驱动程序：
华为数据卡 Linux（点击下载文件）。请参阅下载.usbmodem.com
3）安装
