USB 3.0 Via VL805 PCIe card not working

[1fallen]

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:

02:00.0 USB controller: VIA Technologies, Inc. VL805 USB 3.0 Host Controller (rev 01)

and with lsusb I get:

Bus 003 Device 002: ID 2109:3431 VIA Labs, Inc. Hub

My grub file looks like this:

# 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'


GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=Ubuntu\ Kylin
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX="iommu=soft"
GRUB_CMDLINE_LINUX="intel_iommu=off"

#GRUB_GFXMODE=640x480


# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true


# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"


# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

Does anyone have any other suggestions?

I don't know why this is taking so long to implement (Since the year 2012) into the kernels, but see if this helps by adding "pci=nomsi" to the boot parameters in grub.conf. And don't forget to update grub Also don't forget to disable iommu in your bios.
So where your looks lie this "GRUB_CMDLINE_LINUX="intel_iommu=off" "
try changing "iommu=off" to "pci=nomsi"

I tried that and it didn't work

My BIOS sees the PCI Card as a USB card, but it does not detect any drive I plug in. I have disabled all Intel VT options in the BIOS.

I managed to fix the issue in Arch Linux by updating the firmware (using a proprietary software in Windows) of the VL805.
My version of the firmware (013600 vs 013704) was older than the new one.

Note that to update the firmware, you need to unninstall the windows driver in the device manager, I've had some issues updating it.

This was the response of VIA tech support when I asked them for Linux issues:

Hi,

VL805 is working well on Fedora 4.13.9-300. fc27.x86_64 .
And we also test on Fedora 4.13.16-100. fc25.x86_64 .
The function is ok, USB device can be recognized under VL805.
This issue should be possibly related to AMD driver behavior

Test condition in VLI:
CPU = Intel i3-8100
Motherboard : MSI Z370 Gaming M5

You can download the latest firmware update tool for VL805 and check the function.
User guide is stored in the folder.
This tool only support on Windows-based.

If there is any question, please contact me.

Thanks.

I Hope my message helps other people, since there aren't any other place I've found that shows the true sollution.
