I cannot connect to BeagleBone Black(BBB)'s Cloud9 via USB-NIC on Ubuntu Server 18.04 LTS.
As a result, I found the reason for these issue.
BBB’s USB-NIC has not been enable.
Of course, I done shell mkudevrule.sh, but the BBB’s USB-NIC do not work well.
So I have let USB-NIC be enable with modifiying the file /etc/netplan/50-cloud-init.yaml such as below
The NIC name “enp0s29f7u2i2” is very important.
The “enp0s29f7u2i2” uses USB driver “cdc_ether”.
I have very so much effort to investigate the BBB’s USB-NIC name “enp0s29f7u2i2” with RHEL7 rule.
