This is all correct and expected.

This on the other hand is far less than what should happen.  Among else you
should get one or two "selfID" IRQ events which contain 2 selfIDs --- one
of the FireWire controller and one of the camera.  After that there should
be a bunch of AT and AR events when firewire-core probes the camera.
Finally, firewire-core should report something like "created device fw1:
GUID 003053.........., S400".

This not happening could be caused by
  - defect of the FireWire port of the PC,
  - cable defect,
  - defect of the FireWire port or of the logic board of the camera,
  - insufficient power supply of the camera.
