I have a Dell computer which I bought right before the USB 2.0 technology came out. I want to upgrade to USB 2.0 because USB 1.1 is too slow with the things I do with my computer. However, I have no slots available in the back of my computer to put any new USB 2.0 cards in. My question is that my Dell computer has 2 USB ports in the front and 4 in the back of the computer (all 1.1). Is there anyway to replace the existing USB with the new 2.0? If not, how could I work around not having any slots open but wanting to upgrade to 2.0? Any help would be great! Thanks guys!
