[ovirt-users] hostusb hook - VM device errors in Windows VM

[Steve Dainard]

The USB section is the same on both guests:

    <controller type='usb' index='0'>
      <alias name='usb0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x01'
function='0x2'/>
    </controller>

    <hostdev mode='subsystem' type='usb' managed='no'>
      <source>
        <vendor id='0x05dc'/>
        <product id='0xc75c'/>
        <address bus='2' device='10'/>
      </source>
      <alias name='hostdev0'/>
    </hostdev>

I thought it might be a Windows issue, I've tried on both Win7 64 and
2008R2 64 with the same result. At one point there was a notification
bubble that the USB device can run faster - which I thought might mean the
Windows guest was provided a USB v1 controller.

I've attached both the xml's if you think there might be something I'm not
seeing.

Thanks,
Steve
