Third monitor hdmi -> usb3 not working

[mahesh]

Hi you all,
I just received my new third Samsung external monitor to attach to my laptop.
It works great but having "only" one hdmi on my laptop I bought a super cheap
hdmi -> usb3 adapter.
It worked fine with windows, because once connected it has an internal usb storage
with the win drivers, but when I rebooted with Ubuntu everything changed.
the kernel recognizes it
