My system has Windows 10 Pro 20H2, Mathematica 11.1.1.0 and the following external controllers plus Loupedeck Live:

enter image description here

1- Why do the following commands work:

a)

enter image description here

These don't:

b)

enter image description here

These don't update in Dynamic:

c)

enter image description here

This one works for the Joystick T.16000M (the first device that has "X Axis" etc), although the Slider doesn't work as it is expected (instead of presenting its value it updates like a joystick):

d)

enter image description here

And this doesn't work:

e)

enter image description here

?

2- Why ControllerInformation doesn't find Loupedeck Live?

3- Why data from Microsoft Hardware USB Mouse controls (1029 controls!) is not updated in Dynamic?

4- Why except for the multimedia controls none of the keys of Gaming Keyboard G610 are even presented, much less updated?

  1. Product ID is not the index for the controller. i.e. ControllerInformation[] => "Controller Device #"
  2. The Windows FrontEnd no longer supports 3DConnexions devices.
  3. I assume that Loupedeck Live is not a DirectInput based device. If it is not listed in the Input tab in dxdiag.exe, then it will not be enumerated in ControllerInformation[].
  4. It's not uncommon for a device's driver to advertise more controls then it actually supports.
