The maximum amount of data that can be sent to an InputDevice via InputDevice.SendHapticBuffer.
If the InputDevice receives an amount of data greater than this, then InputDevice.SendHapticBuffer fails and a rumble is not triggered. Check that the device supports haptic buffers via InputDevice.TryGetHapticCapabilities and HapticCapabilities.supportsBuffer. Will be set to 0 if HapticCapabilities.supportsBuffer is false.
