PCIe USB Controller card passthrough.

[edd666999]

System Hardware:

CPU: Epyc 7532
RAM: 128GB DDR4-3200 ECC
MOBO: SuperMicro H11ssl rev2
PCI-e Devices: RTX 2060, SAS2008 x2, Sonnet USB3-PRO-4P10-E USB 3.1 (4port Dual Controller), Hyper m.2 Gen4.

Proxmox 8.1.3
Ive got Truenas setup and functioning.

I'm attempting to setup a windows VM, managed to get GPU passthrough working perfectly following various forums posts, Thanks!

I'm struggling to get my Sonnet USB3-PRO-4P10-E USB 3.1 PCIe card to pass through and function. Windows sees it but Code 43's it.

Bare with me I'm at the beginning of my uphill journey to use Linux

I believe this is correct based of when passing my GPU though? Kernal driver as vfio-pci.

blacklist nouveau
blacklist nvidia
blacklist ASMedia

I added ASMedia to /etc/modprobe.d/blacklist.conf but not sure if that was correct, again just going from GPU passthrough.

I added options vfio-pci ids=1b21:2142 to /etc/modprobe.d/vfio.conf I believe this is so Proxmox doesn't grab it before the VM? I've read this should be needed?

/etc/pve/qemu-server/101.conf

hostpci0: 0000:81:00,pcie=1 is the GPU
hostpci1: 0000:86:00,pcie=1 is one of the ASM2142/ASM3142 USB 3.1 Host Controllers

If it makes a difference, when I try to boot the machine with a usb drive in this PCIe card it attempts to boot from it.

Any advice would be most appreciated!

annnnd Its not going to work based on this guys experience

I do wonder because I picked it up super cheap from amazon warehouse if this has been passed through a number of users trying it in the various hypervisors unsuccessfully

There are some USB controllers that are known to work but you have to make sure that the manufacturer did no change the hardware without notice. Search this forum and the level1techs VFIO forum for suggestions.
