My Dell Dimension 5100c is supposed to have USB 2.0... but it's complaining. The message says: This USB device can perform faster if you connect it to a hi-speed USB 2.0 port. For a list of available ports, click here. What device is it talking about??? All my ports are supposed to be USB 2.0! Is the message in error? When I click, I get a diagram that I don't understand. Are my USB devices running at the 2.0 hi-speed or am I getting only 1.1 speed? I've seen some explanations regarding this but I didn't understand them either! Thanx in advance for any help!
