  firewire_ohci bug (Failed to reset ohci card)

Status in linux package in Ubuntu:

Bug description:
  I'm trying to set up an external firewire audio interface. The
  interface (Presonus FP10) has been "Reported to work" with ffado (see

  Posible duplicate of bug #1163320, but i want to apport a full report
  so i'm creating this new one

  This problem happened on an Ubuntu 12.04.2 LTS system (Release:
  12.04). Ubuntu Studio amd64.

  While expecting the audio interface to be mounted at "/dev/fw0" or
  something like that, it was not.

  I would like to help debugging this but i need some guidance because
  my knowledge about linux system is limited. Please tell me what can i
  do to help solving this. While waiting some response, i'm going to try
  with a newer kernel release as suggested on the coments of bug
  #1163320 and i will inform the results.
