So couple of years ago I decided to virtualize my desktop environment. We can solve most of these problems by passing through an entire USB controller in a different way in a future post.NOTE: The latest UnRaid version should support TPM out of the box, you may rather have a look at that one. A USB controller cannot be assigned in this manner.The Unraid menu must be used to do the assignment.A manual operation must be performed whenever a new device is added to the VM.However, this configuration leaves some functionality on the table: This gets you about 50% of the way to a bare-metal feeling VM. These two configurations are the most basic configurations that you can have with USB devices and a VM in Unraid. The wheel worked only once both of these devices were connected. Unraid then showed another device: “Thrustmaster T300 Wheel”. When plugged in, Unraid showed one device at first “Thrustmaster FFB Device”. I especially encountered this issue when plugging in my Thrustmaster T300 racing wheel. I have also noticed that some devices have their own internal hubs, which mean that they may show another device once initialized. USB devices will then show up directly in the VM settings as below:Īs the note at the bottom of the page will say, sometimes you will need to Attach / Detach / re-Attach the device in order for it to be correctly detected. In order to do this, make sure you have all your USB devices plugged into your machine that you plan to pass through to the VM. This is then easy to configure and connect these to your VM is directly through Unraid’s GUI. The most basic configuration is useful if you have USB devices that will be plugged in all the time. In a future post we’ll take it a step further to get near-baremetal functionality just like we did with the GPU. Here we’ll look at how you can get close to hot-plugging USB devices into a VM. This gets even more complicated when you consider that Unraid boots off a USB device rather than another drive in the system. The host, in this case Unraid, owns, initializes, and configures USB devices by default. However, one thing that is a little awkward are USB devices.
Once you have basic GPU passthrough configured, you can get near bare-metal performance in a VM on Unraid using KVM under the hood.
