Hi,

if I try to start the vm by virt-manager I get this detailed error log:

Fehler beim Starten der Domain: internal error: early end of file from 
monitor: possible problem:
qemu-system-x86_64: -device usb-host,hostbus=1,hostaddr=3,id=hostdev0: 
'usb-host' is not a valid device model name


Traceback (most recent call last):
   File "/usr/share/virt-manager/virtManager/asyncjob.py", line 91, in 
cb_wrapper
     callback(asyncjob, *args, **kwargs)
   File "/usr/share/virt-manager/virtManager/asyncjob.py", line 127, in

problem:
