I think that after this patch, "-nodefaults -device VGA" will get a USB controller that it didn't get before. Perhaps this in vl.c: bool usb_enabled(bool default_usb) { return qemu_opt_get_bool(qemu_get_machine_opts(), "usb", default_usb); } should be bool usb_enabled(bool default_usb) { return qemu_opt_get_bool(qemu_get_machine_opts(), "usb", !no_defaults && default_usb); } ?
