Abstract
Integrated pointing device and integrated keyboard inputs are accepted at a microcontroller that formats the inputs to the HID protocol and embeds the HID formatted inputs into SMBus messages for transfer over an SMBus to processing components of an information handling system. A state machine at the information handling system motherboard extracts the HID packets from the SMBus messages and provides the HID packets to HID registers for use by processing components. Keyboard and pointing device inputs communicated from integrated devices through an SMBus may be treated as trusted data separate from non-trusted inputs through external devices and buses.
