QEMU/KVM USB Passthrough Problem

Post by LinuxLand » 2022/08/24 23:40:26

I have an RODE AI-1 audio interface I need to pass through to a Windows 10 guest. It only shows up as a composite device. Unfortunately I don't have another Windows 10 machine to try this on. I'm confident the audio interface works as I can pass it to an Ubuntu guest and record successfully. I can also plug it into a Windows 11 surface and record. I think the hardware is good and probably the virtualization piece is OK. I suspect there may be something in the USB controller that doesn't work right with Windows 10 or maybe the audio interface is not compatible for some reason. RODE says Windows 10 1803 and later which I have. How can I troubleshoot this? What could cause this problem? I do plan to check the firmware of the audio interface. I do have USB 3 controller in my VMs and I did try USB 2 controller as well. Both give the same results in this case.
