You say "USB Master-USB Master" cable. Which one?
I didn't buy online but from local computer store.
This page describes what I bought.
https://www.castleproductshop.com/products/Plugable-Windows-
Transfer-Cable-for-Windows-10-8-1-8-7-Vista-XP-Includes/588583685
The description says, in part:
"Supported by Linux kernel 3.0 and later as a high-speed virtual network
interface, no special file transfer support."
That implies the cable should provide a network interface to both sides.
What happens when you plug it in? Look in dmesg (near the bottom right
after you plug it in) and you should see something that implies a network
interface has been created.
I found /usr/share/bash-completion/completions/dmesg dated last year.
It was not changed when I plugged or unplugged the cable.
HOWEVER, MATE's Network Icon never showed completion.
Am I looking in right place?
I did a similar exercise yesterday using "lsusb -t" and "lsusb -v"
The relevant extracts are:> With mouse connected, plugin left end of cable
richard@debian-jan13:~$ lsusb -t
