Abstract
A method of setting a key mapping used to generate key information from a keyboard responsive to manipulation of a key on the keyboard is described. A connected keyboard device having a programmable component is detected. A keyboard map usage corresponding to the detected keyboard device is determined. The keyboard map usage is transmitted to the programmable component of the keyboard device replacing a default keyboard map usage on the programmable component. The transmitted keyboard map usage may include a key matrix usage, a key matrix usage and a key matrix offset, or a plurality of key matrix usages. The keyboard map usage may remap one, some, or all of the keys on the keyboard. A corresponding keyboard, computer readable medium, and computer system for use with the present invention are also described.
