ok.

Usually I test with the drivers shipped by the operating system, i.e.
linux kernel or windows 8 (or newer).

Generic xhci drivers should work with any xhci controller, no matter

Is the usb keyboard enough to trigger this?

enabling usb_xhci_* trace events would be more helpful than DEBUG_XHCI
(see qemu.git/docs/tracing.txt).
