If Logic is not connecting to Raven and the Transport and Faders are not functioning, then there is likely a problem with V-Control and Logic communication. To reset the Logic Control Surfaces go to Logic Pro X->Controller Surface-Setup.
Select all the Controllers and then select "Delete" from the edit drop menu.
Re-Launch Logic Pro X and select "Add" when the V-control message pops up..
Double check V-Control Setups to see that Logic and Raven are being seen by V-Control..
