imx8mp evk PORT2(otg) - 4G LTE

[ylmzhsn_]

Hi NXP,

Can't get list (dev/ttyUSB0..1..2..3..4) when I plug in imx8mpevk usb modem. When I use the lsusb command, I see that the device is detected and there is no problem.

***********

CONFIG_USB_ACM:
This driver supports USB modems and ISDN adapters which support the
Communication Device Class Abstract Control Model interface.
Please read <file:Documentation/usb/acm.txt> for details.
Device Drivers --->
[*] USB support --->
        USB Modem (CDC ACM) support

***********

I am attaching the imx8mpevk log.
