I have a new computer with an Asus p8z68-v le + Intel 2500 + 8GB of RAM.
I installed Ubuntu without any issue but the USB3 (from the mother board - on the back of the computer) don't work.
I plug a USB stick noting, I plug my USB3 external drive nothing, but when I plug them in the USB2 everything works perfectly.
I ran all updates also and everything is up to date. What am I missing?
