Greetings ☹

I’m facing an issue with my Huawei 4G USB Dongle (Zowee Technology model) on a Raspberry Pi 4 running balenaOS. On one device, the modem is recognized correctly as an Ethernet device:

nmcli d

DEVICE TYPE STATE CONNECTION  
enp1s0u1u3 ethernet connected Wired connection 1

However, on another device, while `lsusb` detects the modem:

Bus 001 Device 004: ID 3566:2001 Mobile Mobile

I have followed the documentation on the setting up its and its working on one device and not the other

Could anyone provide guidance on ensuring balenaOS correctly recognizes the Dongle as on the Raspberry Pi 4? Any assistance or suggestions would be greatly appreciated.

Thank you!

Hello! What version(s) of balenaOS are each Pi 4 running? (It would be good to know if they are the same or different) Also, can you provide the board revision for each device? (You can type the command `cat /proc/cpuinfo` in the Host OS terminal to get that info, for instance “Model : Raspberry Pi 4 Model B Rev 1.5”)
