Qualcomm Snapdragon X55 5G does not turn on

[Nikolaj Hansen]

The system tries to configure the device, but never manages to turn on the hardware. I have to do it by hand by using

sudo qmicli -p -d /dev/wwan0mbim0 --device-open-auto --dms-foxconn-set-fcc-authentication=0

I also have a case here on ask ubuntu:
