> 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
fixed in 1.5.991 - now all works fine here thx!
