Support Ubuntu 20.04 LTS (Focal Fossa)

[polrus]

I have the same issue

I installed flex, bison, libelf-dev
but still the installation fails.

I bought 3 x displaylink devices last week - pls support and update the driver for the newest kernel

Also it is a shame that in 2020 and Ubuntu 20.04 installation instruction is dated 2014 and mentiones ubuntu 14 :/
