Hi,

I purchased a Dell Dimension 4700 (desktop) a few years ago and it came with a Dell cordless mouse and keyboard.  I just purchased a Dell XPS laptop and a Logitech cordless keyboard and mouse.  I want to use the Logitech (new one) on my Dell Dimension 4700 and I tried to plug in the old Dell cordless mouse and keyboard to my daughter's old computer - and HP Pavillion 750 - so she could have cordless too.  It does not work and it has one USB cord.  Do I need to download a driver for this?  How can I get this to work?  Sorry this is so long and sorry if this is a dumb question! 

Any help would be greatly appreciated!!
