Currently, -device xxx still can't work well for ppc64 platform. It's better use legacy USB option with default for ppc64.
This patch is to legacy USB option with default for ppc64.

Can you explain what difference you're expecting ? This patch does not change the way the command line args are generated. It merely prevents you from listing multiple <controller> elements in the XML. If you're expecting any kind of functional change, you need more than what you have there.
