Intel p4 3.00 ghz. 915 motherboard 512 mb ddr memor the above is the configuration. Recently I wanted to upgrade the firmware of my mp3 player. at that time, a message popped up saying that I am upgrading from a slow usb port and I should upgrade from a faster port and it even showed a list of faster usb ports which are available in my pc. But I couldn't understand which usb port in the front or in the back or even in the front there are two. Now I want to know the specific usb port which is fastest? Can somebody help? I am very newbe in hardware.
