The game supports 6-dof input devices. However, it seems like KSP cannot grab a device with the usage Page of 0x01(Generic Desktop) and usage of 0x08(Multi-Axis Controller), with the axis(s) of 0x30 to 0x35 (X, Y, Z, and Rx, Ry and Rz). Should it be of Page 0x05 (Game Controls) and usage of 0x01 (3D Game Controller)? With the axis(s) of 0x21 to 0x26 (turn, pitch, roll, moveX, moveY, ad moveZ)?

I have currently decided to use 4 knobs (infinite rotating) and a ThumbPointer. The three knobs will come together into what I call a "3D trackball" fixture that track rotation in X,Y, and Z. The ThumbPointer will track movement (of the stick) in X and Y direction and a final knob responsible for another Z axis. Which give the 6 degrees of freedom (XYZ, RxRyRz) required for said input device. However, I assume that people will prefer one method of input to be more suitable to one than another. Which input (Rotation or Pan) should the "3D TrackBall" module be used for?

I am trying to make a USB HID 6 dof input device using Arduino Leonardo to "enhance my gameplay" and do other cool stuff. Such as panning spreadsheets. The latter which is irrelevant for this purpose. What exactly is the "6 dof input device" that KSP is expecting (on Windows)? What Class (definition)? What associated Descriptors? What Device ID? I have already made a successful HID Gamepad, the XpandShield MK II. Which works with Simpleplanes and Kerbal Space Program (and other games). I have a 3-axis gyro accelerometer, the 24 buttons on the MK II, the 2 Thumbsticks, the 2 Sliders, and 5 Knobs. I believe I have plenty of input to make it work.
