FireWire ports can easily get damaged, so try the second one on the option card of your mixer. The FireWire cable probably will still be ok, but it might be worth to try another cable. If your mixer otherwise is ok (audio, faders, bars etc.), the problem probably is on the computer side. Hopefully the above mentioned article from the Knowledge Base will be helpful. Asl the "related articles" might be interesting. If nothing works I would suggest contacting PreSonus technical support, as it says at the end of the article. Computer problems can be difficult. It is better to get some personal assistance.

i've tried several steps from the list above such as deleting all of the UC registry in the roaming folder and reinstalling, chanigng the IEEE 1394 driver and changing ports but still my pc doesn't recognize the console, it doesn't show up on the other devices section on the devide manager... i'm really frustrated, it was working perfectly until last week.. and i'm not from US so i can't get direct service, pls helpppp :/
