New comment by ahesford on void-packages repository https://github.com/void-linux/void-packages/issues/33548#issuecomment-944981696 Comment: Do you have `elogind` installed and enabled? That may set necessary ACLs on USB devices to enable host -> guest USB forwarding. Otherwise, you probably need to work some magic with udev. (USB forwarding also fails to work for me with `virt-viewer` because I don't use `elogind`.)
