I have a late 2005 G5, and I turned the computer on, immediately plugged in my iphone and walked out of the room. I walked back in later to find that my bluetooth and USB ports aren't working. I can't reset PRAM because no USB. Any ideas? Not desperate here, the computers old but I would like to get another year out of her. Thanks! Have a reason what it might be---I recently pwned my iphone and in order to put the phone into DFU mode i had to install some patch of 10.5.5 And that patch has to do with the USB ports i believe. Installing now and will let you know if I've answered my own question.
