This could indicate a timing problem after re-probing the modem ports if the modem rebooted itself. If all TTY ports are exposed but MM doesn't handle the modem, that's a good explanation. We would need MM debug logs to check this further, could you setup the daemon to run --debug (and e.g. --log-file=[PATH] to avoid using syslog, if your system log is being rotated) -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
