This patch seems to be mixing two things:
1) Disabling USB host support. If System z mainframes don't have USB
support, it doesn't make much sense to enable USB host passthrough.
2) Disabling USB support for guest machines. Wasn't there a recent
virtio-usb RFC? In that case it would very well be possible to connect
virtual USB devices (including smartcard) to the virtio s390 machine.
Regards,
Andreas
