Differences among the USB ports on the new MBP 2010

hello. on new 17" mbp, there 3 usb ports on left. there differences? recall reading somewhere 1 of ports can used power device requires more power (e.g. portable hard drive draws power laptop). reason asking using special software requires users plug in usb hardware key. plugged in port closer palm rest area. did not work. then, plugged usb port near magsafe connector. works. wonder if 1 near magsafe more powerful..
