爱立信 MiniPCI (USB) 3G 调制解调器在启动后取消注册

我有一个内置爱立信 F3507g 3G 调制解调器（MiniPCI 插槽但 USB 连接），它在启动时初始化但之后立即注销 - 来自 dmesg：

并且该设备没有显示在 rfkill 列表中：

我花了好几个小时试图自己解决这个问题，但一无所获。同一个调制解调器曾经在另一台装有较早内核的笔记本电脑上使用。我在网上找到了一些诱人的线索，但没有找到如何解决问题的建议，例如：

爱立信 F3507g (0bdb:1900) - 虽然已注册 USB ACM 设备，但 NetworkManager 中不显示

我将非常感激任何可能有助于解决此问题的建议。也许这是一个 udev 问题？

编辑：根据要求，输出# udevadm test /sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4
