HIDP_STATUS_INVALID_REPORT_TYPE

Collection does not contain a report of the specified type.

HIDP_STATUS_REPORT_DOES_NOT_EXIST

ReportType is not valid.

HIDP_STATUS_BUFFER_TOO_SMALL

Button in an array is not set to On (one) because the array fields are already used to index other buttons.

DataList parameter has set a button to Off (zero), but the button is already set to Off.

HIDP_STATUS_DATA_INDEX_NOT_FOUND

Data index of a DataList member is not valid.

HIDP_STATUS_INCOMPATIBLE_REPORT_ID
