Hi,

What kind of device do you assign to the guest?

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
what pci ids it has.

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).
cheers,
