      @rlyons20 soooo... xe pusb-list only exposes STORAGE devices. I verified by plugging in a USB thumb drive, and that shows up.

      So, my use case of running HomeAssistant as a VM with Zigbee/Zwave USB devices is probably dead in the water.

      That's disappointing...

        You might modify the filter to get your dongle detected 🙂

          I wrote a script to set up USB device passthrough for a specific device by name to a specific VM by name in the same basic way the XCP-ng Centre UI does it when you follow the steps described in the original post. Here's the script: https://gist.github.com/gpoole/c89807e9de9cb5c87bbcc2da27e0c3e4

          Are those the commands you're looking for @olivierlambert?

          Either way hopefully useful to anyone who wants to do this without using XCP-ng Centre. I've found it needs to be done every boot, so the script is intended to be something I can quickly SSH in and run. I'm sure it could be automated properly but works for me.

            Thanks for the commands. I just find it weird you need to do it at each boot, I don't remember having to do it here 🤔

              @gpoole Thank you! I'm sure this will be quite useful in my homelab, but maybe not at work just yet... particularly because I am hopeful Olivier and Vates are able to integrate this into XOA.

              This is because I am looking into integrating at least one HSM into our xcp-ng infrastructure, and the $650 USB-A YubiHSM2 is quite attractive. It would be great to be able to reliably pass this through via XOA to a Windows Server VM. I could imagine this use case being potentially important for small-medium sized companies looking for alternatives to typical expensive HSMs.

                I would agree this would be great for the Z-wave/Zigbee dongles in Home Automation.

                Right now I'm working on a small homelab that can pass through the intel Quicksync to a Plex server and the USB to support HA.

                Having this in XOA/XOCE, even XO-lite (understandably not really a "lite" feature).

                  I am also interested in this feature.

                  We use XCP-NG to run the virtual hosts in our DMZ. As you can imagine, the DMZ is completely separated from our internal network and the only way to transfer a file to a virtual server is to physically connect a usb drive to a host.

                  We use Xen Orchestra for everything except this. When we need to mount a USB drive we have to physically connect a laptop to the DMZ network and then attach the USB drive with XCP-NG Center.

                    @cyrus104 @olivierlambert I'm also interested in USB support, and specifically USB dongle connectivity for HomeAsssistant.

                    @olivierlambert , you mentioned filter modification. is that at the xen level? Similar to many, i'm at the beginner level- I'm willing to tackle a problem or provide specification for further development, but i'm not sure where to start.

                        For usb passthrough we are using USB redirector over network
                        For anything storage related we use something like this:

                        mkdir /adm/passSR
                        
                        passUUID=`xe sr-create name-label="Direct access SR" name-description="Direct acces to hdd with simlink" type=udev content-type=disk device-config:location=/adm/passSR`
                        
                        ln -s /dev/sdb /adm/passSR/sdb
                        
                        xe sr-scan uuid=$passUUID
                        xe vdi-list sr-uuid=$passUUID
                        

                        Remember to replace /dev/sdb with your device.
