Hi all,
One more observation: When running Mac OS guests with -mac99,via=pmu, the guest is presented with a usb-mouse and usb-kbd, while -mac99 provides cuda mouse/kbd.
If I run with via=pmu, the mouse/kbd will not work when passing through the usb headset.
Only when I keep interrupting by pressing a volume button on the headset, the mouse moves. So it seems Qemu does not iterate getting interrupts over multiple devices.
Best,
Howard
