PROTOCOLS
Connector
Defined in fuchsia.device.fs/connector.fidl
A connector lets a client forward the server end of a protocol.
Connect
Forward a server end of a protocol so that it can be connected.
- request
serverthe server end of the protocol to be served. The FIDL protocol that this speaks is determined out-of-band.
- response This function has no response. The function is one-way to match the pipelining behaviors of other virtual filesystems.

1 | connector | client_end:Connector | This is the connector to be installed in devfs. |
2 | class_name | string:255 | This is the class name for installing this node in devfs. The node will be placed within /dev/class/{class_name}. If |
3 | inspect | handle<vmo> | This is a vmo of inspect data that will be installed in devfs. Optional: If this is not provided then the devfs's inspect data will be empty. |
4 | connector_supports | ConnectionType | The connection types that are supported by the |connector| given. The driver framework should handle connection types that are not supported by the connector. If not provided, only the device type is assumed as supported by the connector. Added: HEAD |
