Abstract
A baseboard management controller in an information handling system receives a human interface device input and converts the human interface device input into a human interface device scan code for storage at a human interface device descriptor buffer. The baseboard management controller determines whether or not the human interface device descriptor buffer is full and copying, when the human interface device descriptor buffer is full, the human interface scan codes in the human interface device descriptor buffer to a memory segment and sending an error code to a host system. The baseboard management controller also clears the human interface device descriptor buffer and re-populates the human interface device descriptor buffer with the human interface device scan code and the human interface device scan codes from the memory segment.
