I'm still new with unraid and trying a few things. I was using a Linux VM for about 2 weeks and it was working great, except for the sound. Researching I found out that I should passthrough the USB controller to the machine. I watched the space invader one video about the subject, but it was a bit old and some things looks different and I think I'm missing something.
The problem is: 9 out of 10 times I start the VM with the usb controller attached the host machine reboots. If I dettach the usb controller from the VM it works 100% of the time. After a few reboots it eventually works and the sound problem is also resolved.
I used the scripts space invader one provided to know which usb port belongs to each controller. I used the system devices screen to bind the controllers at boot:
IOMMU group 16:[1022:1639] 30:00.3 USB controller: Advanced Micro Devices, Inc. [AMD] Renoir/Cezanne USB 3.1
This controller is bound to vfio, connected USB devices are not visible.
IOMMU group 17:[1022:1639] 30:00.4 USB controller: Advanced Micro Devices, Inc. [AMD] Renoir/Cezanne USB 3.1
This controller is bound to vfio, connected USB devices are not visible.
The usb controller where the usb stick is at is another one:
IOMMU group 11:[1022:43d5] 16:00.0 USB controller: Advanced Micro Devices, Inc. [AMD] 400 Series Chipset USB 3.1 xHCI Compliant Host Controller (rev 01)
Bus 001 Device 001 Port 1-0 ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002 Port 1-7 ID 0781:5567 SanDisk Corp. Cruzer Blade. <<<<< this one
Bus 001 Device 003 Port 1-10 ID 1050:0402 Yubico.com Yubikey 4/5 U2F
Bus 002 Device 001 Port 2-0 ID 1d6b:0003 Linux Foundation 3.0 root hub
[...]
What might be the problem? Researching I found some people saying that they were able to fix some problems with an pcie usb controller, but I don't know if will be the case.
Some information about the environment:
Host:
CPU: Ryzen 4600g
MB: MSI B450M-A PRO MAX
I'm also passing through the GPU (EVGA GTX 1060 6GB)
