You may be hitting the "FCC authentication" issue, although to know for sure we need to see the ModemManager and NetworkManager debug logs (this doesn't look like a kernel issue). Could you get them following these steps? https://www.freedesktop.org/wiki/Software/ModemManager/Debugging/ Once you have them, please use the ModemManager-devel mailing list, as this isn't a kernel issue: https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel -- Aleksander https://aleksander.es -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
