Really? Then what the heck was the point of the 4 USB ports on the originals?
You can use the USB ports for more things than just controllers. I have one used for an IR receiver, another for a keyboard, a third with the mini-USB controller charger cord, and then the 4th came into use just last week when someone had some photos on a thumb drive they wanted to show me. Oh, another time my friend wanted to see some photos he took earlier in the day but he had an xD card which isn't readable by the PS3's reader. I was able to plug my computer's external memory card reader into the PS3 without any trouble.
