I don't know if maybe this could be your error:

RTX 2XXX also have a usb device, maybe is the same with RTX 3XXX if this is the case ensure to add it, also remember to use the "multifunction" there is a video from spaceinvader one that explains how to passthrough correctly RTX 2xxx.

Do you have VT-D or the equivalent for AMD (AMD-V?) fully enabled in the BIOS

In my experience it's often switched off to allow Ryzen master to run

VT-D is set to Enabled in my bios.

I get the same error when i try to pass my rtx 2070 with all of its usb controllers

I'm not sure why I read this as AMD earlier.

 

Anyhow, I note you say that both GPU's and some PCI-E bus slots are in IOMMU group 1. 

Devices really need to be seperated into different IOMMU groups to pass through

 

Eg. from my server, 

image.thumb.png.2ce727d3cae71857611ef1ce254e0ccb.png

 

Have you tried PCIe ACS overide in Settings > VM Manager ?

This may break the devices into more manageable groups although it is a bit of a hack which tells the OS to assume it can talk to devices independently when they aren't actually reporting that as possible so your milage may vary. 

 

You may need to check the BIOS for any other functions in addition to VT-d which support virtualisation as some BIOS need multiple settings to fully support VM's.

 

'IOAPIC 24-119 Entries' - 'Enable' may help as it uses an alternative to IRQ for multifunction devices... but that's a long shot, I suspect it is more linked to the cards sharing the same IOMMU.
