Full cyclic communication has not yet taken
place.
Possible causes:
• The controller is not transferring any set-

• During isochronous operation, no global con-
trol (GC) or a faulty global control (GC) is
transferred by the controller.
• "Shared Device" is selected (p8929 = 2) and
only one controller is connected.
