This bug is not exclusive to qemu/kvm; it affects any software that deals with USB devices in userspace. I consider any USB /dev node not group-owned by plugdev to be a release-critical bug. You should put the following command into some kind of cron job:
ls -gR /dev/usb* /dev/bus/usb|grep -v ^d|grep -qv plugdev && echo Bug 60273 is not fixed!
