Canoscan Lide 30 - want to use on laptop running XP Pro

Did you restart your computer after you downloaded your drivers and software? Did you select the correct operating system? Make sure the USB cable is plugged into the computer and the scanner...Open the toolbox and click scan or save and check to see if the scanner makes any noise or lights up...If you are using Windows XP then make sure you have downloaded the "TWAIN" driver and the "WIA" driver (two seperate downloads)
