Beating my head against the wall with this. I am running the latest PVE on my Dell R620, been about a year since I first installed it. I have a Windows 10 VM which I am trying to pass a 4-port USB 3 card to, but it almost never functions properly.
I have the system set up already for PCIe pass through, i.e. the IOMMU stuff and so on. Have been using a GPU passthrough to this same VM since I first installed it, works brilliantly. I also have a PCIe LSI HBA card passed through to a TrueNAS VM perfectly fine (entire controller passed through).
But this PCIe card is weird. It is showing up as a Renesas SH7757 controller. Running lspci -v shows these entries associated with the card (I am deleting extraneous lines to save space):
Pausing for a minute - I am noticing the 'kernel driver in use' not being the VFIO one. It's a 4-port hub so I was not shocked to see 4 entries, but the last one has a different ID format (maybe that's just because it's hex sequence?), and does not mention 'kernel driver in use' at all. It also is classified as a bridge and not a switch, like the preceding 3 entries. So, for passing through the card in its entirety, I am thinking the last entry may signify the heart of the card?
If not....farther down the list generated by running lspci, there is another entry from this card:
Getting the device IDs:
So I added the device IDs to my vfio.conf file:
When I go into my VM's hardware menu in the main UI, I can only see that 42:00 entry as selectable/detected. I have played with different combination of ROM-bar, all functions, etc on that passthrough options menu.
Sometimes flash drives show up fine in the VM, but most of the time, they do not. External hard drives (the reason I installed this card) have almost no chance of ever appearing in the VM.
Proxmox seems to think it all worked fine: when I plug in a USB hard drive and it's not showing up to the Windows VM, I go back to the PVE hardware settings for the VM. Try adding a USB device: I thought maybe if it's not being passed through, I could see it here as a selectable option under "Use USB Vendor/Device ID" but it doesn't show up. So at some level, Proxmox thinks it's been passed through and is no longer available as an option. When the card (42:00) is removed from the hardware selection menu of the VM, I can select the hard drive, as now Proxmox is the one working with the PCIe card. But this is not what I am trying to do as my solution every time I plug something in to that card.
Does this sound like a junk card, or is it a junk config? It was a budget choice (FebSmart I think) I got for under $20 last year.
