As per the previous email, you should remove the qcom-soc plugin (or just leave it there, up to you), but you should definitely add the generic plugin in your build, as that is the one that will be used. > > ModemManager[7062]: <debug> [000002587.323649] [plugin-manager] successfully > loaded 1 plugins registering 4 subsystems: wwan, rpmsg, net, qrtr > > ModemManager[7062]: <debug> [000002587.324407] service name > 'org.freedesktop.ModemManager1' was acquired > So MM is anyway processing events for wwan and net subsystems, but you're not getting notified of any port addition on MM daemon startup. That could mean your kernel doesn't have proper support for the WWAN subsystem or the Qualcomm mhi drivers. What is the version of your kernel? You need at least 5.13, or otherwise backport drivers to older versions. Kristian has backports for 5.4 and 4.14 which work pretty well: https://github.com/kristrev/mhi-for-kernel-4.14 https://github.com/kristrev/mhi-for-kernel-5.4 -- Aleksander https://aleksander.es
