我在 Proxmox 上有一个非常基本的服务器 Ubuntu 22.04.2 LTS，运行 Docker，使用 USB 3G 调制解调器作为 SMS 网关。它工作了几个星期，但今天它停止作为设备“/dev/ttyUSB0”工作。我最近没有安装任何东西，也许我只是升级了操作系统，但dmesg一旦我连接它，就会看到该设备：
[ 290.515190] usb 2-1: new high-speed USB device number 2 using xhci_hcd

过了一段时间：

这里有一些其他的输出：

我可以重新安装操作系统，但同样的问题会第二次出现，如果我找不到根本原因，它可能会再次发生。有人知道根本原因吗？
更新：
一旦复制该行为（通过 ProxMox 连接 USB 设备），journalctl -b就不会似乎显示任何有用的东西：

然后，brltty没有安装（我已经检查过了）：
# dpkg -l | grep brltty
