I have had these wrorking on XP after much trouble, but after working for about 2 months I have identified that it freezes my mouse on startup if it is connected. It only unfreezes when I disconnect it. I have uninstalled and now having problems installing, (see my thread). However, you might try the Belkin site and download drivers form there. Uninstall and then reinstall uisng the downloaded drivers, it worked for me, 1st time!
