ProtocolModeConfig
It is often necessary to override OS behavior in order to get around OS (and application) level bugs. Forcing either Boot mode (6KRO) and Report mode (NKRO) are often necessary for NKRO compatible keyboards. Mice that support boot mode are not common and generally only useful for legacy OSs.
