USB mouse config

Hi all, I am having a hard time setting up my logitech usb mouse on my sony vaio laptop. I can see the mouse in the usb list, but it doesnt seem to work. I checked to see if all the modules were loaded, they are. I looked at the help and only found some work arounds however they didnot seem to help. Does anyone have any experience using a usb mouse with a laptop? Thanks Brian
