Input Event Monitoring

# Show raw input events

Key Code Mapping

Common key codes from Kobo Remote:

• 0x6c (108) = KEY_RIGHT - Right button
• 0x67 (103) = KEY_UP - Up button
• Other buttons map to standard Linux input key codes

This allows button remapping and isolated input handling separate from the device’s built-in controls.
