Issue Description
ksriram@tegra-ubuntu:~$ lsusb
Bus 001 Device 038: ID 2047:0013 Texas Instruments
Bus 001 Device 037: ID 0451:2046 Texas Instruments, Inc.
ksriram@tegra-ubuntu:~$ ls /dev/ttyACM*
ls: cannot access ‘/dev/ttyACM*’: No such file or directory

Trying to connect an external sensor to the DRIVE kit and would like to be able to get ACM module on it so we can transmit serial info from it.

Error String
ksriram@tegra-ubuntu:~$ ls /dev/ttyUSB*
ls: cannot access ‘/dev/ttyUSB*’: No such file or directory
ksriram@tegra-ubuntu:~$ ls /dev/ttyACM*
ls: cannot access ‘/dev/ttyACM*’: No such file or directory

Is it possible to install this using cdc-acm.ko or some other way?

Adding a comment to show that the kernel version is

Dear ksriram,
Please see if
Connecting GPS USB devices to NVIDIA DRIVE AGX Orin helps.

Is the file within a docker container or can I find it in any repo?
Do you have a link to this file?
