Renesas uPD720201 USB 3.0 PCI card passthrough

[ms4sman]

Hi all,

 

A while back I bought a Renesas uPD720201 USB 3.0 PCI card for my Windows 10 VM so I could pass it through for some hotpluggable USB ports. It worked great, but more recently I'm starting to try to switch entirely over to Manjaro for everything but gaming, and I'd like to give those hotpluggable ports to the Manjaro VM instead. I added the card to the XML according to this post, just like I did to add it to Windows, and it seems to attach to the machine on startup, because all devices plugged into it become unavailable for use elsewhere, but Manjaro doesn't seem to know what to do with it. It doesn't show up in lspci and devices plugged into it don't show up in lsusb either. It is in it's own IOMMU group. I think I'm probably missing something obvious but I can't think what. I'd appreciate any help!

Let me know if any more information is needed, I am happy to provide it!

Very strange. Have you tried passing it through to a different linux VM? I have cards with this chipset working in linux mint 18.3.

Sorry for the late reply, I haven't had a chance to try another VM, I will do that now and get back to you.

 

Thanks!

I have just tried it out in a Fedora VM I had set up, and it works fine there. So it seems to just be Manjaro. I'm going to try it again in another Manjaro VM without any other PCI devices passed through and a few other combos just to see if it makes any difference.

 

EDIT: Could it be to do with SeaBIOS or anything? I ended up having to use SeaBIOS for Manjaro, it didn't want to work with me on OVMF.

I suppose its possible. I've had GPU passthrough problems solved by using SeaBios but I thought that was from vbios being tainted during host boot and would not think it would make any difference with usb cards. I'd honestly suspect something else was changed perhaps indirectly by the seabios change.
