Hello Everybody! I need your help please!
So I try the aforementioned solution but it doesn’t seem to “fully” work with my usb card:
This card has 4 USB 3.0 with 4 controllers (1 each). I bought it specially for my unRaid VMs ! Indeed, all USB controllers (and PCI bridge - not sure it’s a good thing here) appear in different IOMMU group.
I’ve been trying to give 2 of my Windows 10 VM two USB each but while the pass through devices appear in each VM device manager, they do no work: I get a exclamation mark and it says device could not be started/do not operate (I’ve installed the genuine drivers from the card website).
I’ve also tried passing the PCI bridge behind the corresponding controller but I get the error in unRAID saying device does not exist.
Thanks to lspci and memory addressing I was able to pinpoint which USB stands behind which PCI bridge (letters).

Hypothesis #1 : should PCI bridge and USB controllers be part of the same iommu group ?
Hypothesis #2 : should I stub the card to hide it from UnRaid at boot ?
So here goes my headache… all yours now….you have 2 hours !
