I'm no networking guru, but I would just try and see what happens step-by-step, then focus on where the first error is found. Can follow steps below or the ones in the NiLuJe package...
Assuming you already have NickelMenu entries:
# display IP Address of Kobo
menu_item :main :IP Address :cmd_output :500:/sbin/ifconfig | /usr/bin/awk '/inet addr/{print substr($2,6)}'

Connect PC and Kobo to WiFi hotspot.
On Kobo, toggle telnet and SSH and display IP Address.
From PC, telnet to your Kobo e.g.:
$ telnet 192.168.43.5 2023
Trying 192.168.43.5...
Connected to 192.168.43.5.

Now, following the instructions from here, except skipping the modules part...
Hacking the Kobo Clara HD – 4.1: Telnet over USB
https://www.yingtongli.me/blog/2018/...elnet-usb.html
On my Clara HD, I need to install modules or else I get the following result:
# ifconfig usb0 192.168.2.2
ifconfig: SIOCSIFADDR: No such device
If modules exist or your kernel has the built-in capability (CONFIG_USB_U_ETHER=y implies built-in, =m implies module) hopefully you get something like:
# ifconfig usb0 192.168.2.2
# ifconfig

***
EDIT :
* right after I loaded the modules, but BEFORE the "ifconfig usb0 192.168.2.2" command, the USB interface on the Kobo was logged as follows:
# dmesg | grep usb0
usb0: MAC CA:79:8D:D4:F8:14
i.e. the MAC address was assigned to a usb0 port before any ifconfig command was issued.
***
Now connect the USB cable between Kobo and PC.
Now on my Linux PC, the network applet icon on the desktop (/usr/bin/nm-applet from the network-manager-gnome package) would be a spinning progress bar, like it's trying to connect on ethernet.
I click this icon and choose "disconnect".
On PC I enter "sudo ifconfig usb0 192.168.2.1" and I am connected.
Somewhere in the desktop log I see, e.g.:
$ dmesg | grep usb
[ 4338.148728] usb 1-5: new high-speed USB device number 8 using xhci_hcd
[ 4338.299352] usb 1-5: New USB device found, idVendor=0525, idProduct=a4a2, bcdDevice= 4.01

And in the ifconfig I see:
usb0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.2.1 netmask 255.255.255.0 broadcast 192.168.2.255

Now, if I am running an SSH server on the Kobo, then I can connect from the PC over USB, e.g.:
$ ssh root@192.168.2.2 -p 2222
