In my last post I commented about my USB situation, which I hoped would be quickly resolved with a USB expansion card. I picked up this model from Inateck; a 5-port USB A device which would allow me to connect my USB switcher for keyboard & webcam, a headset for gaming, as well as gamepads and wheels.
It arrived with customary Amazon quickness, and I added it to the machine. Slightly annoyingly it (and others) required a power connection from the PSU, as the PCIe slots can’t supply the 5V required. I was out of SATA connectors so this meant running a Molex cable through the case (urgh).
I brought the machine back online and found the new USB device sitting happily in its own IOMMU group, so I bound it to VFIO, rebooted the server, then passed it through to the Windows machine and started it up.
That’s where my troubles began.
