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)?
