// This code makes your Arduino act as a 3DConnexion SpaceMouse (32u4-based board required).
// To make this work you also need to set the USB Vendor ID and Product ID to values matching a real 3DConnexion device.
// You can do this by editing appropriate entries in the boards.txt file in your Arduino installation.
// Example values: vid=0x256f, pid=0xc631 (SpaceMouse Pro Wireless (cabled))
// Then install the 3DxWare software from 3DConnexion on your computer and you can use you Arduino device in software like Fusion 360 as it it were a real SpaceMouse.
