(Sorry for my english 😉 )
Ok.. Problem not solved.
Today i started t my PC and Windows wasn’t able to connect the Exetracker.
The HOTAS wasn’t plugged in, no Logitech-Software on my PC.
(No LED-Lights).
I do hear the sound from Windows, when in plug/unplug the device.
But the Eyetrack-Software doesn’t recognizes the hardware.
My HOTAS is normaly pluged with a active USB 3-Hub. So the power there should not be the problem.
Eyetrakercker also on active USB-Hub or direct.
I also think, that the gaming-Hub does slow down the PC.. probably the mainproblem.
After deinstalling Gaming-Hub, the systemstart is much faster
