I've recently built my first PC and got it all working (yay!) except for the USB 3.0 ports. I don't think any of the USB 3.0 ones are working, there are some in the MB/back and also a couple at the front, I did plug in the USB 3.0 wire from the case to the mb, and made sure the USB 3.0 option is enabled in BIOS. I can't update the mb drivers as there are only options for windows on the msi site. MB is MSI 970 Gaming.If I go into BIOS, I can see the devices I have plugged into the USB 3.0's, but if I try to see them through the command line once booted, they aren't there. I've found this answer to the same problem I'm having, but I'm such a newb I can't figure out how to apply the solution (I did have a go but it didn't work). Could someone please give me the idiots guide on what to do with the below, or another solution if applicable. Bear in mind, total idiots guide, as I've never used linux before.I had the same problem. Resolved it by adding in /etc/default/grub:GRUB_CMDLINE_LINUX=iommu=softThen sudo update-grub, reboot and voil!
