Adding the following lines to guest.xml, works: <controller type='usb' index='0' model='piix3-uhci'> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x2'/> </controller> <controller type='usb' index='1' model='ehci'> <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/> </controller> Many thanks to all for your help. -- CL Martinez carlopmart {at} gmail {d0t} com
