Re[2]: Re[2]: Modem Manager bring up

Sun Feb 27 13:08:44 UTC 2022

Hi Aleksander,

The udev/gudev is up in my system. I have merged the SDX 65 patches, Now the ModemManager is scanning the PCIe devices. However, the "mmcli -L" reported that "no modems were found".  
Any inputs will be appreciated.

Here is the ModemManager logs.
