Are you using something like a USB hub to connect to all of them, or is there something else in common apart from the computer itself?
What do you see if you look at the settings for the USB ports (go to Control panel then "system" then "hardware" then "Device Manager", "Universal Serial Bus Controllers" should be at the bottom.) Is there a yellow question mark there?
