I have recently switched to Ubuntu and decided to install the latest 18.04 version. I managed to find my way through all the hacks and fixes to get it up and running. However, I'm stuck with my USB ports that are not working at all. I have tried switching between both ports, but no luck. However, please note that launching and booting Ubuntu from USB works. However, I can't use the ports after the os has been launched. Here is my configuration.
