New Computer Mouse Won't Work! HELP!

Hey guys and gals,
I just got a new Logitech Wireless Mouse for my laptop. I installed the set-up from the CD and all that, but when I put the USB into either of the two ports I get a message saying that the USB device is not recognized. My flash drive will work on either of the two ports, so I know that it isn't that the ports do not work at all, but it seems that the computer does not know what the device is and I don't know how to make it recognize it.
Any help will be greatly appreciated.
Thanks,
Predaprince
