Startech USB3.1 PCIe card failing to initialize

[EricD]

Running: 5.3.18-2-pve #1 SMP PVE 5.3.18-2 on an AMD Ryzen 9 3900X

I picked up a PEXUS313AC2V card to to pass through to a Windows guest that I need to attach a bunch of USB devices to. Passthrough sort of worked, windows saw both controllers on the card but with the default windows driver the controller would fail with error 43 as soon as something was plugged in. Installing Startech's driver resulted in Windows BSODing about a minute after boot if the card was attached to the VM.

The PCIe card shows up as two PCI devices 10:00 and 11:00, each are in their own IOMMU group.

I do successfully pass through a Radeon 5700XT to this same VM but for testing/debugging I removed the PCI mapping from the VM config.

I gave up on passthrough and figured I'd just see if I could use the extra ports from Linux. After remove the vfio-pci ids from /etc/modprobe.d/vfio.conf I'm seeing the following in dmesg related to the two PCI devices.

I'd love to get this card passed through to the Windows VM but at this point I'd settle for figuring out why Linux doesn't like it.

The ASM1142 is a widely used USB Chipset so there should be no problem this it.
But you can try the Linux kernel 5.4. Maybe this will fix the problem.
I would install the USB card to a fresh installed Ubuntu 19.10 and check if this error can reproduce on this setup.

So I did a bit more digging and apparently it just doesn't like my Valve Index. Not sure why.

I ended up passing through one of the onboard controllers to the VM and am able to use the StarTech card for USB devices used by the host.
