Bad, as this should become 0 and 2 respectively. This is consistent with what you got with the newer kernel: While the camera is connected (and switched on), the bus is permanently reset and never finishes a reset successfully with a self-ID-complete event, after which it would become usable for system software.

This and the fact that you already replaced the cable and also tested a PC-to-laptop connection unsuccessfully leaves pretty much only the conclusion that the port (or the ports) on your FW322/323 based board are dead.
