That is aggravating. I assume you have XP on your notebook as like your desktop ?

I had a similar problem with my MS wireless mouse. Worked like magic on desktop , like you , no driver(s) needed from I'Net. But on the notebook , for some reason , I had to install MS's pgm that controlled the mouse's wheel & what not to get it to work. But you say you did that right ?

I'm afraid this is one of those deals where you are just going to have to take it from step 1 all the way through to what you have already tried again. Somethings missing. Big help huh ?

If you can find the *.inf file for that piece & delete it , then the notebook would have to look at , hopefully , your driver disc to get that info.
