really old version. Aren't you able to upgrade it to something newer, like 0.6.x at least? Of course 1.0.x with libqmi support would be much better anyway, as I see it's a Gobi device. Anyway, there's little we can do without debug logs from ModemManager. You can probably follow the instructions here, but I'm not sure whether they apply to MM 0.4: <a shape="rect" href="https://wiki.gnome.org/Projects/NetworkManager/Debugging" target="_blank">https://wiki.gnome.org/Projects/NetworkManager/Debugging</a> If you're really into trying MM 1.0, use these ones: <a shape="rect" href="http://www.freedesktop.org/wiki/Software/ModemManager/Debugging/" target="_blank">http://www.freedesktop.org/wiki/Software/ModemManager/Debugging/</a> -- Aleksander<div class="yqt2561204746" id="yqtfd23073"> _______________________________________________ ModemManager-devel mailing list <a shape="rect" ymailto="mailto:ModemManager-devel@lists.freedesktop.org" href="mailto:ModemManager-devel@lists.freedesktop.org">ModemManager-devel@lists.freedesktop.org</a> <a shape="rect" href="http://lists.freedesktop.org/mailman/listinfo/modemmanager-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/modemmanager-devel</a> </div> </div> </div> </div> </div> </div></body></html>
