Package: libvirt-bin Version: 1.2.8-3 Severity: normal On a newly installed Jessie amd64 box, USB Host Device passthrough for qemu guests is broken due to qemu-system being unable to access the necessary /dev/bus/usb device files, e.g.

This is somewhat related to #563502, but additionally access fails for non-hot-plugged USB devices (e.g. those plugged in since host machine boot time). Workaround is to chown/chmod the device files manually. Incidentally, PCI device passthrough via vfio works fine on the same machine.
