Comment 45 for bug 156085

openSUSE has a patch at https://bugzilla.novell.com/show_bug.cgi?id=241950 which fixes qemu to use /dev/bus/usb instead of /proc/bus/usb. It doesn't quite apply cleanly to current qemu, but it should be possible to port it without much effort. They may also have a newer version in the package itself.

If someone could get this cleaned up and submitted upstream, and we'll be able to cross qemu (and kvm) off the list of packages affected by this issue.
