Plugins can say "I don't support this specific device", and so in your case you could update the Cinterion plugin so that the specific vid:pid is listed in MM_PLUGIN_FORBIDDEN_PRODUCT_IDS, and then the order of loading of plugins is irrelevant, see: https://www.freedesktop.org/software/ModemManager/api/latest/ref-overview-modem-port-probing.html#id-1.2.5.4. BUT, why is it that the modem cannot be supported by the Cinterion plugin? Which are the commands that are different? Can the Cinterion plugin not be updated to support this new model as well? -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
