我找到了一种使用以下命令手动切换的方法：
usb_modeswitch -v 0x12d1 -p 0x1446 -s 5 -M 55534243000000000000000000000011060000000000000000000000000000，但它的行为有些不稳定 - 有时它会在 5-10 分钟后切换回 CD-ROM 模式。
我还尝试将以下几行添加到/etc/usb_modeswitch.conf：
DefaultVendor= 0x12d1
DefaultProduct= 0x1446
MessageContent="55534243000000000000000000000011060000000000000000000000000000"

GSM 调制解调器在操作系统启动时顺利切换，但在挂起/恢复后它会切换回 CD-ROM 模式...
我希望usb_modeswitch开箱即用，而且我知道它必须以这种方式工作。我在 ubuntu 论坛上找到了以下帖子：华为 E398 无法与 Ubuntu 14.04LTS 一起使用并且该问题看起来很像我的并且仅在 Ubuntu 14.04 上重复出现但没有解决。
