If you try to create a guest with an invalid type or bus, you'll see 
something like the following error:

<input type='invalid' bus='ps2'/>

libvir: Domain Config error : internal error unknown input device type 
'invalid'
error: Failed to define domain from test

---------------

<input type='mouse' bus='invalid'/>

libvir: Domain Config error : internal error unknown input bus type 
'invalid'
error: Failed to define domain from test


------------

If we're unable to get the expected values from the guest, then some 
kind of error in libvirt has occurred.  So setting the caption to 
"Unknown bus Unknown device type" is a fall back in that case.
