Logitech cordless keyboard and mouse

Hello everybody, After updating to SuSE 9.1, I can't use anymore my numerical keypad in X. In version 9.0, I changed the option XkbModel to pc105 (It has 105 keys). And that worked well. Now I am searching for the appropriate configuration files, if possible for "Logitech cordless") or a short and clear description how to configure them. Who is so kind to help me? Henk
