That's not really true, because that timeout is bound to the max time required by ModemManager to probe the AT/QMI/MBIM ports, which I believe is close to those 45s max per port (in parallel). Having an infinite loop there doesn't help, as that max time required by MM is not arbitrary, that's why I suggested incresing the timeout value; maybe some of the ports take up to 45s to probe and we just need a longer timeout when detecting the modem in DBus. -- Aleksander https://aleksander.es
