You can do exactly that
<hostdev mode='capabilities' type='misc'>
<source>
<char>/dev/input/event3</char>
</source>
</hostdev>
or for block devs
<hostdev mode='capabilities' type='storage'>
<source>
<block>/dev/sdf1</block>
</source>
</hostdev>
See:
http://libvirt.org/formatdomain.html#elementsHostDevCaps
The device path you've listed must exist in the host's /dev for this
to work though - we don't make it possible to create devices in the
container which don't exist in the host
