我正在尝试在 Ubuntu 12.10 上运行华为 E173 设备。首先，我尝试在原始 Ubuntu（通过 Wubi 安装）上运行它，没有任何更改。设备在lsusbas处被检测到Bus 003 Device 004: ID 12d1:1c05 Huawei Technologies Co., Ltd. E173s 3G broadband stick (modem on)，但我在任何 /dev/ttyU* 路径上都找不到它（正如我预期的那样，在 ttyUSB0、ttyUSB1...）。然后我尝试使用 trunk NetworkManager 和 ModemManager，结果相同。设备已列出lsusb（这意味着 usb-modechange 工作正常）。
以下是一些可能有助于您调查我的问题的输出：

我还发现了一些奇怪的事情，第一的插入华为 E173 设备我发现一些额外的日志（来自 usbcore）：

编辑：运行最新的 netinstall debian 时出现同样的错误（usb 2-3：坏的 CDC 描述符）。
