I have also enabled DIAGENABLE with AT!CUSTOM=“DIAGENABLE”,1.
When the modem is turned on, The linux OS gives me 2 serial devices (/dev/ttyUSB0 and 1) and /dev/cdc-wdm0. I can send and receive AT commands via /dev/ttyUSB0. Nothing seems to happen on ttyUSB1.
Where can I see diagnostic messages?
What is the purpose of the second serial port?
Should I have more serial ports? I expected a new one to appear when I turned the diagenable on…
I am trying to use Sierra Wireless EM9293 on Linux Ubuntu(Ubuntu 24.04.3 LTS), when i open the QXDM i cannot see any diag port to capture the logging in QXDM i see below error.
Can you please share how to make this diag port visible on Linux system and which driver we need to install to make diag port port visible and please share the steps to install the required driver

I installed the drivers by doing sudo make and sudo make install then reboot the PC, still cannot detect the port in QXDM
please find the dmesg below can you please let me know if any other drivers missing or any setting needed to detect the port in QXDM? please find the snippet of QXDM
