# Deadband: reconstructing GameSir and Logitech device configuration

> Deadband reconstructs configuration exchanges for GameSir controllers and the Logitech G502 X LIGHTSPEED mouse in a Linux GUI. Its research notes connect USB identities, hidraw and evdev probing, USB captures and device registers to controls for lighting, profiles, remapping, curves and macros.
