qmi_wwan fails with error -22

All the driver info now looks good to me. Yes, qmicli or mbimcli should work. I cannot explain why they don't.  Which could mean that there is something we don't see... Do you have any other processes opening the /dev/cdc-wdm0 devices? lsof is a good way to find out. Could you run ModemManager with --debug? Maybe it will tell us more about the problem.

I am running out of ideas here...
