 - Includes utility to configure revburner tachometer
 - Can send data to any serial device. So far only tested with arduino. Includes sample arduino sketch for sim lights.
 - The support for haptic bass shakers is limited and needs the most work. So far the engine rev is a simple sine wave, which I find convincing. The gear shift event works but not convincing enough for me.

 - hidapi - usb hid devices
 - libusb - used by hidapi
 - portaudio - sound devices (haptic bass shakers)
