host usb hook
=============

          !!! Disclaimer !!!
*******************************************
The host side usb support wasn't thoroughly
tests in kvm!
*******************************************

add hosts usb device/s to VM:

<hostdev mode='subsystem' type='usb'>
    <source>
        <vendor id='0x1234'/>
        <product id='0xbeef'/>
    </source>
</hostdev>

syntax:
    hostusb=0x1234:0xbeef&0x2222:0xabaa
    i.e.
    hostusb=VendorId:ProductId (can add more then one with '&' separator)

Note:
    The VM must be pinned to host and this hook will
    fail any migration attempt.
