tried with 1.4.12 and with 1.5.990 ..nothing works

Are you running ModemManager as root user?

> Are you running ModemManager as root user?

yes, as root 
what i see - something is happened when modemmanager started to use  the new mbim-proxy  with mm versions higher than v1.4.6
i was compiled all versions of modemmanager (1.4.4 1.4.6 1.4.12 and 1.5.990) with libmbim 1.12.4
the only one that have worked was 1.4.4  
the intersting thing, i guess, in the mm output is

ModemManager[5613]: <warn>  Could not grab port (usbmisc/cdc-wdm0)   for v1.4.6 and above >>> mm is failing
ModemManager[9177]: [/dev/cdc-wdm0] Queried max control for v1.4.4 and below >>> mm is OK
