I got a USB 3.0 Card the other day and I found that it was only working when I booted into Windows (which I seldom do). However, I would really like for it to work on Ubuntu since I use it the majority of the time. My computer is a Dell Optiplex 980 full tower and I am on Ubuntu Kylin 16.04.
I followed the suggestion here: https://bbs.archlinux.org/viewtopic.php?id=214293
but adding the iommu soft to grub did not work. I disabled Intel VT, and it still didn't work.
Multiple people have said that they have gotten it to work on their computer, but it does not work on mine.
with lspci I get:
Code:
02:00.0 USB controller: VIA Technologies, Inc. VL805 USB 3.0 Host Controller (rev 01)
and with lsusb I get:
Code:
Bus 003 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
My grub file looks like this:
Code:
# If you change this file, run 'update-grub' afterwards to update# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'

Does anyone have any other suggestions?
