Describe the Bug

When connecting via VoidLink with Sunshine configured to use libvirtualhid, the driver instantiates a Virtual HID Framework (VHF) absolute pointing / touch / digitizer device on the host system. Emulation frontends like RetroBat / EmulationStation read this generic raw input pointer ID as an active physical Lightgun (hid vhf), even when no pointer/touch inputs are actively being sent by the client.

Expected Behavior

libvirtualhid should either expose virtual gamepads without forcing a persistent absolute pointing/digitizer HID device node when touch passthrough is unused, or expose HID IDs that identify strictly as standard gamepads/mice rather than triggering generic lightgun/digitizer auto-detection.

Additional Context

This issue occurs if Sunshine is running, even if no client is connected.
