that explained your problem where you are still using the old driver which does not include the PID 90d3:

usb:v1199p90D3d*dc*dsc*dp*ic*isc*ip*in*

24

Yes, do you know how I can "force"the use of the qcserial? Or how to fix the issue? Thanks again for your support

25

have you rename the original one in /lib/modules/5.15.61-v8+/kernel/drivers/usb/serial/ and then copy your newly compiled binary driver to this path?

Before that, you might need to disconnect USB cable of EM9 module and “rmmod qcserial”.

26

I’ve done this but still can’t see

usb:v1199p90D3d*dc*dsc*dp*ic*isc*ip*in*

Maybe I miss some steps

27

Have you tried directly “insmod” your binary driver?

28

I tried but still have the issue

29

I think you should ask in some raspberry pi forum

30

ok, thank you again for your support

31

the issue seems modem manager, by disabling the AT commands work without any issue … but I can’t no more use the cellular connectivity…

32

Strange that modem manager would block insmod

Btw, you can use mbimcli to establish data connection

Thanks, I am using this approach, a bit boring compared to the modem manager way but at least it works
