I bought a tractor controller s4 mk2 from a third party, but unfortunately I have the problem that when I turn on the controller it flashes briefly everywhere and in the end only the master indicator remains.
I use a laptop with Wind 10, USB 2.0 and an original charger.
When it comes to software, I'm not sure which one is right.
Since I'm not familiar with the variety, I would be happy to receive help.
Maybe you will find it here:

Thanks only the problem is that the s4 mk2 is simply not elegant from my laptop… Maybe it is due to Windows 10? Definitely need help; have been trying for days.
Could it be that your USB port is not delivering enough juice? Changed to a different USB port? And try to use the laptop with a power supply. Or try on another laptop. Otherwise I can't think of anything else. 😕
Since he has already written that the controller is used with a power supply (and the S4 can't be switched on without a power supply), this problem can be ruled out.
The Kontrol S4 MKII basically only works with a full version of Traktor Pro 2 or 3. Without the right DJ software, the controller does nothing at all. It is normal for the LEDs to (almost) all go out again after switching on.
You can check whether the controller is recognized by the computer in the device management in Windows. There the controller appears regularly as an audio (output) device.
We recommend purchasing Traktor Pro3. If the controller is then connected via USB and switched on, it is automatically recognized by the software and fully supported. Further settings are then usually unnecessary.
Ok, then we rule out that the USB port could be defective despite the power supply on the controller. 🙄
I find that an exciting conclusion. That was not what your answer was about before, but rather that the USB port "does not bring enough juice". They just have absolutely nothing to do with each other and are not based on a defect in the port, but on insufficient voltage output.
From your statement I gather that you would not describe a USB port that supplies too little voltage as defective. So now you are mixing up voltage and current. As far as I know, the official specification for USB2 provides a maximum of 500mA and for USB3 a maximum of 900mA. In contrast, a fixed nominal value of 5V is specified for the voltage. This results in an error pattern for the voltage if it is too low. So your comment on this is: "… And does not focus on a defect in the port, but on insufficient voltage output." complete nonsense.
But I'm generous today and throw a possibly defective or too long USB cable into the room.
