I’m not seeing any qmi_wwan devices and I’m not getting a wwan0 device either. I checked that the EM7411 is still set for 1,3,10D and it is. But this is what I’m now getting when I plug in the EM7411 to the SOM.

It looks to me like I should be getting some kind of usb device to use but I’m not seeing anything popup in my /dev list:
