text: my usb2.0 ports no longer realize they are 2.0. how can i fix that? i'm on a thinkpad t40 which i know should have usb2.0, yet any time i try to use my flash drive it says, "this device could perform faster... if you connected to a usb 2.0 port" which it should already be in. usually, only one usb port on a laptop is 2.0 compliant, you have to find out which one it is. also, if you are putting anything between the usb port on the computer and the usb drive, like an external hub, make sure that it is 2.0 compliant. plugging a 1.1 hub into  2.0 port makes it all run at 1.1, thus anything you connect that is 2.0 will bring up that message.  lastly, go into the device manager and look to see in usb devices if there is a usb 2.0 driver listed there, if not then contact the laptop manufacturer to see if they can help you get it back.
