Problem Suse 8.2 loosing my keyboard

Hi, i have a great problem with my new Suse 8.2 linux box. Once in a while i loose my Keyboard connection so that i cannot type anything anymore. The only thing i can do is to reset my machine. Nothing helps since i can=B4t type anything. My Mouse works fine, and if i reboot my Kde System the x-server hangs with a blank screen. I habe the cordless logitech keyboard an mouse bundle. Has anyone of you had a similar problem? Thanx Hape
