20240105移远的4G模块EC20在Ubuntu 20.04.6 LTS下使用联通5G卡上网的步骤
2024/1/5 10:11

缘起：需要在Firefly的AIO-3399J开发板上调试移远的4G模块EC20（Android10/11/12），需要现在先测试EC20的好坏！
陶老板告诉我找一个USB2.0转mini PCIE的转接板接上去，这样就可以直接测试了。

请【严重注意】注意SIM卡的方向！

【需要2G的大卡，也就是卡套外面还有卡套！】

昨晚WIN10上通过USB延长线接上去明显需要驱动程序。
今天在Ubuntu20.04.6下的USB3.0接口【蓝色口】插入【装上底板】EC20。

通过lsusb命令，很容易发现已经找到了EC20了。

插入EC20之前：
