1) In theory, no, you wouldn't need to install any software. However, from here I cannot tell you why you have those unrecognized USB devices in your system.
2) The LCD protocols shown are those where the presence (connection) of the display device cannot be detected via classic methods. So we need to show them always in order to give users a chance to enable those protocols when they own a display device.
3) You can right-click on one of the LCD tabs (e.g. Crystalfontz) --> Show All. That way all interfaces will be visible, but you will still not be able to use the Turing module simply because it would require a Turing USB device to be present in the system. In which case -- when the device is present -- the LCD tab corresponding to the Turing interface is properly shown.
