T2 stopped working, but why?

[Joker]

Good day everybody,

I had the following problem.

I have always used the T2 in combination with the XIM4, I have a new workplace and have therefore moved the setup.
I always thought it was silly to add the T2 and the XIM4 as well, so I was like, okay, you're only going to use the T2 on the Series X from now on.

So I connected the T2 to the same port (with exactly the same cable; T2 supplied cable) on the Series X.
Have keyboard connected to PORT A, Port B with Series X controller and then connect the mouse there.
So that was done, I thought to myself now only set the configs on the computer.

So the "PROG" port is connected with the cable that I have always used (which ALWAYS worked) and the T2 lights up yellow where it was always green.

I thought okay maybe he just doesn't understand the situation and try to use another cable(s).
However, I have the feeling that Gtuner does not want to connect T2. (picture is attached)

What am I doing wrong now?
It used to work and now all of a sudden it doesn't?

Eject the SD card and then plug in PROG.
You may need to format the SD card it it continues.
