Notify a `queue` for the device. Primarily used for black-box testing.

void Ready (uint32_t negotiated_features, ReadyCallback callback)

Ready a device. This provides the set of `negotiated_features` that the

driver and device have agreed upon.

void Start (::fuchsia::virtualization::hardware::StartInfo start_info, bool enable_input, bool enable_verbose_logging, StartCallback callback)
