The Vero4K seems to power it and not connect it. (Is this cause the power cord is not connected?)
osmc@osmc:~$ lsusb
-bash: lsusb: command not found
The keyboard is to old for me to have any such manual, sorry.
This guy seems to get it working
but I have tried everything he did and nothing, but I guess this means the Vero4K can power it? It is based on RPi3 right?
