Only the first four controller devices are available to be selected

Squadrons doesn't recognize my USB devices. 
Yes, there are a lot of them.
No, that shouldn't matter at all.
See attached pictures.
Windows, DCS, MSFS 2020, FSX, X-Plane, and every other program under the sun sees all game controllers.

Squadrons only sees the two listed.

I've unplugged all other USB HIDs and Squadrons will see the pedals, stick, and throttle.

This just means your code is trash, because I should be able to select which controls I want to use from all available controls.
Any decent sim can manage this.
I shouldn't have to unplug my controllers to play a game.

So the question is: how can one re-arrange the list of USB devices?  I believe the issue is the order in which Windows sees them.
