I have a new computer with an Asus P8Z68-V LE + Intel i2500 + 8GB of RAM.
I installed Ubuntu without any issue, but the USB3 (from the motherboard - on the back of the computer) doesn't work.
I plug a USB stick -- nothing, I plug my USB3 external drive -- nothing, when I plug them into the USB2 and everything works perfectly.
Also, I ran all updates and everything is up to date.
What am I missing?
