i have a thumb usb drive. made the folder PS3 and sub folder UPDATE. put the file in there and plug the usb in my ps3. i try to update via storage device and it doesn't recognize it. I have played movies of the thumb drive so i know the ps3 recogizes it. I have tried several times....any suggestions besides the obvious ones which I have did. I have a 2.5 yr old fat style ps3 if that matters.
