我从 Aliexpress 购买了这个 Dongle：在此处输入链接描述
芯片：高通9600
我在 x86_64 cpu 上运行 Ubuntu 18.04.6 LTS 插入后，我得到了：

我可以通过 Web 浏览器连接到 192.168.100.1 并打开仪表板面板，在那里我可以设置宽带连接（APN 等）。但我没有连接到互联网。
因此，从这里我开始阅读和研究如何探测该设备以使其工作。
我阅读了很多关于如何向调制解调器发送 AT 命令的文章，但都没有成功。我不明白这是否与加载的驱动程序/模块有关：

我尝试绑定到 usbserial 驱动程序
modprobe usbserial vendor=0x05c6 product=0x9024
如果我得到的是 2 个设备：
# sudo lsusb -t
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M
|__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/8p, 480M
|__ Port 1: Dev 10, If 0, Class=Wireless, Driver=rndis_host, 480M

|__ Port 1: Dev 10, If 2, Class=Vendor Specific Class, Driver=usbserial_generic, 480M
/dev/ttyUSB0 也已创建。
但我无法访问它或向它发送任何 AT 命令。
我使用了 minicom 2.7.1，在尝试了一些功能后收到了此消息：
Cannot open /dev/ttyUSB0!
所以，我的问题是：我如何探测/设置这个设备？
谢谢
