-==== - lsusb ====
+执行 lsusb 命令，如果出现如下内容则模块已经成功被 Linux 系统识别到。
+  Bus 002 Device 009: ID 2c7c:0125 Quectel Wireless Solutions Co., Ltd. EC25 LTE modem
+其中，0x2C7C 和 0x0125 分别是 Quectel EC25/EC20 R2.0 的 VID 和 PID 编号。
+==== - AT指令接口 ====
+当连接模块并加载 USB 驱动成功后，在 /dev 目录下将会创建出几个 tty 设备节点。例如 /dev/ttyUSB2 是 AT 指令的控制端口。
