request for using X55 with Carbon X1 Gen9 under debian bookworm

[Becker, Jochen]

Hello Developers,

I have an Lenovo Carbon X1 Gen9 with a Snapdragon X55 WWAN card, and it will not work under debian bookworm.
I followed all instructions and currently I am down, since working 5 days on that problem.
So i decided to write an email

modemmanager 1.18.8-1
qmi-utils 1.30.6-1

Do you have an idea?

Greatings
Jochen
