Unable to see the USB device in /dev (EM7411 by Sierra Wireless modem connected to IMX8MP)

I have an EM7411 by Sierra Wireless modem connected to IMX8MP.
I was able to load the cdc_mbim and qcserial driver to the board.

This has the word document explaning the problem with imageslink text

Once both drivers are loaded, I ran the lsusb to verify however I do not get the correct output, below is my output:

After further investigation found that the driver has not been loaded for the USB serial endpoints due to missing vid:pid values in the qcserial driver. To temporarily add the values, I used “echo 1199 9071 > /sys/bus/usb-serial/drivers/qcserial/new_id”
After all this I am still missing the usb device from the /dev directory.

The link I referred: Techship - FAQ - How to use Sierra Wireless MC/EM74 and EM75 series cellular modules in Linux with the MBIM interface?
Please let me know what I am missing.

Greetings @Saksham98123!

Another customer has had issues with another Sierra modem operating via USB and was able to solve this by disconnecting/covering pin 23 from the mini PCI-e connector: Connect Sierra Wireless AirPrime MC7455 to IMX 8 - Technical Support - Toradex Community

This solution - covering some PCIe-related pins - is also reported on other forums. Let me know if that works for you.
