USB Tethering not working in jetson nano

I have a Jetson nano that is running Ubuntu 18.04 LTS. I need internet access on the jetson. Currently, the only internet connection that I have is on my phone. I tried to tether my phone to the jetson via USB, but I cannot get internet access to the device. Jetson recognized my phone as a tethered device. lsusb gives the following output:

ifconfig gives the following output:

currently I have connected my laptop to the Jetson device via the micro-USB port on the Jetson.

Please let me know if you need anymore data. And thank you :)

Hi,
Not sure if it is the cause, but micro B port on Jetson Nano only can operate in device mode. If USB Tethering requires Nano to be run as host, the function is not supported.

its not the micro usb port that im intending to use. its the usb 3.0 ports. i am connecting a rndis device to one of the usb ports to get interner=t access

Hi,
By connecting Nano to your host laptop, you should see README-usb-dev-mode.txt
There is guidance of using Ethernet protocol. Please tale a look.

Thank you, that is exactly how i am using it right now. But i would really like to have something like a usb modem to go on to the device and provide direct internet access to the jetson. Could this be any driver related issue

Hi,
We have verified the case of plugging usb ethernet adapter to the type A port. For plugging a phone, it probably requires additional driver. May need other users to share experience.

Hi,
There is an upstream patch. Please check
