The Microsoft pointing device or keyboard may not function at all

When you try to use one of the Microsoft pointing devices or keyboards that are listed in the "Applies to" section, the device may not function at all. Alternatively, the device may not be detected by Microsoft Windows.

This issue may occur if the device signal is not detected by the signal transceiver.
