I suspect he wants to pass something like an XBox controller. It would actually be a very good usecase for Bluetooth passthrough. If he is using Linux guests, he could use virtio-input-host-pci. For Windows, we could also pass it through as an HID device, using something like virtio-input-host-pci but for USB. It wouldn't be hard to implement, but you'd have to write a converter from Linux evdev descriptors to USB HID descriptors.
