我做了很多研究，想将我的旧华为 e1550 调制解调器与 ubuntu 14.04 操作系统连接起来，我找到了几个可能的解决方案，但没有一个能起作用。因此，当我通过lsusb命令将调制解调器连接到 USB 端口时，我得到了以下结果：
Bus 002 Device 010: ID 12d1:1446 Huawei Technologies Co., Ltd. Broadband
stick (modem on)
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

这是dmesg日志：

我已经尝试过sudo modprobe option，sudo usb_modeswitch -v 0x12d1 -p 1446 -R -W我已经创建了像这样的 udev 规则 ->
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1446", RUN+="/lib/udev/usb_modeswitch --vendor 0x12d1 --product 0x1446 --type option-zerocd"
但什么都没起作用。调制解调器没有显示。请帮帮我。
