Public methods
onDisconnected
abstract fun onDisconnected(): Unit
Called when the HID device has been closed or disconnected.
This is the definitive signal that the device session has ended. All registered listeners (including this instance) are automatically unregistered, and the device is no longer usable.
onError
abstract fun onError(cause: Exception): Unit
Called when an error occurs during HID input report processing.
This callback is purely informative and never unregisters listeners. On non-fatal errors, report processing continues. On fatal errors, this callback is immediately followed by an explicit onDisconnected() invocation.
| Parameters | |

Exception: The exception describing the error. This value cannot be null. |
onInputReport
abstract fun onInputReport(report: Report): Unit
Called when an input report is received from the HID device.
