Hi all,
I’ve been running VFIO in various capacities for about 4 years now, and my current system which is a Ryzen based unRAID server has been going strong for a couple years. I’m working on switching from my Windows 10 VM to a Manjaro VM as my daily driver.
One of the pieces of hardware I had passed directly to Windows 10 was a 4 port Renesas uPD720201 USB 3.0 PCI card to allow for four hot-pluggable USB ports, and it worked great. However, when I assign it to my Manjaro VM, it doesn’t seem to know what to do with the card. It grabs hold of it, the USB devices plugged into it are no longer available to attach to other VMs once Manjaro starts up, but the PCI card doesn’t appear in lspci, and the USB devices don’t appear in lsusb and I’m at a loss as to why.
Any suggestions? It’s likely something obvious, as I’m no expert in Linux yet, that’s why I’m trying to switch to it fulltime, to learn it better.
The device is in its own IOMMU group:
IOMMU group 28: [1912:0014] 07:00.0 USB controller: Renesas Technology Corp. uPD720201 USB 3.0 Host Controller (rev 03)
