Hello,
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.
