Do you need a USB for a PS3 controller

this question wasn't answered @ all! Gamestop makes a controller for the PS3 and it does not have a USB/miniusb plug-in @ all! "If the contoller does not have a usb port it isn't a PS3 controller, sorry its a fact"?????? That remark helps about this much..."0"!!!!!!!!
I bought one of these crap controllers that doesn't seem to be able to sync with the PS3. However i just found something that mentioned "bluetooth scan", so im gonna go try that before trying to return it to gamestop AGAIN! THEY TOLD ME THEY CAN'T TAKE IT BACK EVEN THOUGH IT DOESN'T SEEM TO BE ABLE TO SYNC/WORK @ ALL WITH THE PS3!!! tHIS IS BS!!!!
