Olá galera!

Sou novo no mundo linux e comecei utilizar o ubuntu 18.04 (gnome) no qual me deparei com o primeiro problema. Simplesmente o sistema não reconhece nenhum dispositivo conectado em uma porta USB 2.0 mas reconhece as duas portas USB 3.0.

Procurei por vários posta na internet mas infelizmente não consegui resolver o problema.

Como está em inglês, vou deixar os passos traduzidos:

- pressione Ctrl+Alt+T para abrir o terminal

- rode o seguinte comando:

sudo gedit /etc/default/grub

- edite as aspas vazias na linha que deve ficar assim:

GRUB_CMDLINE_LINUX="iommu=soft"

- salve e rode no terminal:

sudo update-grub

- reinicie e teste as USB 2.0 e 3.0
