I just did a conversion from an Acronis echo backup of a windows XP machine, and I am having trouble getting the USB device to pass through (in this case a USB license dongle). I added the USB controller, but the USB devices will not show up in the list.
I can see the dongle from a fresh install of Server 2008, but not this machine.
One note, when opening up the settings I get this error:
"An IDE controller is found but the virtual machine does not support this option."
After clicking the "OK" button, I get this:
"A flat backing option was not found"
Any ideas?
