Writing an Input Module The sample module introduced here is called idiom (Input Device for Intercepting Output of Mice), The sample module registers itself with the USB kernel subsystem as a mouse driver and with the input management subsystem as a keyboard driver. idiom translates mouse movement events into keyboard input events: it reports arrow events to the input system according to how the physical mouse is moved. -Writing an Input Module The sample module i ntroduced here is called idiom (Input Device fo r Intercepting Output of Mice) The sample module registers itself with the USB kernel subsystem as a mouse driver and with the i Input management subsystem as a keyboard driver . idiom translates into mouse movement events k eyboard input events : it reports arrow events to the input system ACCO rding to how the physical mouse is moved.
