so... my problem is with this little guy that turned into a big headache. I tried EVERY forum post and countless Linux Distributions and i had the same problem, i cant make this Ralink wifi dongle to work, the dongle dont even appear in lsusb or dmesg. Is like the ubuntu dont want to see him connected... Btw, the dongle works, i tried in my main computer with windows 10 Home and the windows recognize the dongle. But in Linux it's completely no-deal, i running Ubuntu 18.04 in my old laptop, an Dell Inspiron N5110(obs: i fisically removed the native laptop wifi card because the antenna cables where damaged).
This is my last weapon to try to win this fight against a wifi dongle, i expect you guys could help me, thanks.
And sorry for my english, it isn't my main language.
