imx8 running Linux not able to recognize USB ACM device

Mojosound — Tue, 07 Nov 2023 17:55:10 GMT

I am working on a project where we are changing from an older imx6 architecture (not NXP) to an NXP based imx8 based system. The imx6 system was running a stock Debian and included support for the usb_acm driver. I cannot find support for the usb_acm driver in the github repository. The board I am testing on is not recognizing the device. This is a key peripheral to our system and a show stopper if not supported. The device being connected has a STM32 processor and should come up as a comm port. I did a search but could not find an answer to this. If I missed it, please provide the link. Otherwise, how can I resolve this? Thanks.

Evaluation board used is 8MPLUSLPD4-EVK.

The driver name is different in github. Instead of usb_acm the driver is cdc-acm.
