USB Ethernet device not connecting

Question

I have a USB Ethernet Device that when I connect to several Ubuntu 18.04 machines (fresh install) it attaches fine. For example I see it as a network interface

4: usb0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN group default qlen 1000
    link/ether b6:30:f8:52:01:76 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::b430:f8ff:fe52:176/64 scope link
       valid_lft forever preferred_lft forever

Here is the dmesg log when I plug in the device to a working setup:

[   66.350555] usb 1-1.2: new high-speed USB device number 3 using xhci_hcd
[   66.451897] usb 1-1.2: New USB device found, idVendor=1cf2, idProduct=a4a2, bcdDevice= 3.14
[   66.451918] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0

[   66.521772] usbcore: registered new interface driver cdc_eem

However, when I attach the device to a Nvidia Jetson running Ubuntu 18.04 it does not show up as an NIC and I get these logs in dmesg (missing device registration):

[  153.497340] usb 1-2.4: new high-speed USB device number 5 using tegra-xusb
[  153.519325] usb 1-2.4: New USB device found, idVendor=1cf2, idProduct=a4a2

[  153.519381] usb 1-2.4: Manufacturer: Linux 3.14.70-fslc+g34b9927 with 2184000.usb

Any suggestions or insight on troubleshooting this issue?

Edit: Results of sudo dmesg | grep cdc on a working device:

pi@rpi10:~$ sudo dmesg | grep cdc

Does this answer your question? My wireless/WiFi connection does not work. What information is needed to diagnose the issue? — waltinator, Aug 10 '22 at 22:09
Please edit your question to include the result of the terminal command: sudo dmesg | grep cdc Welcome to Ask Ubuntu. — chili555, Aug 10 '22 at 23:04
Plugged into the Jetson; i.e. not working device, what does this report? sudo modprobe cdc_eem — chili555, Aug 11 '22 at 00:40
modprobe: FATAL: Module cdc_eem not found in directory /lib/modules/4.9.253-tegra So seems I need to install this module. I'm looking into how to do that and will give that a shot. — jacali, Aug 12 '22 at 13:05
On the not working device, run: sudo dpkg -s linux-modules-extra-$(uname -r) | grep Status and show us the resukt. — chili555, Aug 12 '22 at 15:11
dpkg-query: package 'linux-modules-extra-4.9.253-tegra' is not installed and no information is available Use dpkg --info (= dpkg-deb --info) to examine archive files, and dpkg --contents (= dpkg-deb --contents) to list their contents.``` — jacali, Aug 12 '22 at 15:26
4.9.253-tegra is not an official Ubuntu kernel or flavor. It is highly customized for Jetson devices. I haven't any further suggestions. If this were Ubuntu, I'd say that driver modules are in linux-moduless-extra and to install it. Sorry. — chili555, Aug 12 '22 at 15:37
