**Traktor Kontrol S4 - Master LED-Light, controller won’t connect** Hi! I’ve been experiencing a problem lately with my Traktor Kontrol S4. When I plug my controller, all the lights blinks one time, like it does on every start-up of the controller. But when that’s done, the only thing flashing is the Master(USB?)-LED. What does this mean? I’ve restarted the controller, Traktor 2 and my computer. I’ve also checked device manager and I CAN see the controller in the USB-hub section. I’ve seen a couple of threads on different forums with this problem, but all in all, no solutions. So does anybody have an Idea what this could be? ---

that normally means it aint plugged into your computer. make sure its plugged in correctly, it can be a bit stiff around the back of the s4. have you tried a different usb port and/or a different usb cable ? ps. i know ya can see the device in the usb hub section, but i dont know what else it could be other than a loose connection or inactive usb port pps. welcome to the forums. and if i aint helping ya, im sure one of the bigger boys will be along shortly to help ya out. hope ya figue it out ---

Thanks for your answer : ) As I mentioned, I CAN find the controller in the Device Manager, so I doubt it’s faulty connected. In addition I’ve tried to change USB-Port several times, but still nothin’ :\ And also this has started happening recently, so it has worked fine earlier. And last, please excuse my bad english ^^ Thanks! : ) ---

I also have this problem occasionally. Restarting TPS2 normally solves it but can be annoying. ---

Have you tried a different cable? Is it plugged into your computer or a hub? Have you tried a different port on your computer? Does the computer have some type of power save feature on the USB’s? ---

No hub, I’ve tried switching USB-ports like 20 times. No power-saving modes : ) Yes, I’ve tried switching cable two times. I’m 90% sure that it’s not my cable and not my USB-ports. As I mentioned, this started yesterday for real. (It has happened a few times earlier, but then I just re-plugged/restarted the controller, and everything was fine.) EDIT: And yeah, I doubt it’s the cable. As I mentioned in the first post I can find the controller in Device Manager, with no problems detected 🙂 ---

is you cable loose on any end ??? i know sometimes USBs can tend to loosen up after a while also, as i said earlier, make sure your cable is pushed in fully into your S4, it is quite a tight fit. other than that, im stumped to what your issue may be ---

Ok, for the last time: It can’t be the USB-cable. IF the cable was the problem, it would show an error in Device Manager, or not be connected at all. This HAS happened a couple of times earlier, but a restart of either Traktor or the controller fixed that. ---

Im thinking if you should reinstall the whole thing, culd be a driver error. Happen to me once and all i did was a reinstall. just make sure you backup your traktor files. ---

while it may not be the cable that light flashes fro a specific reason so there’s something along those lines that causes the problem. I think reinstalling may be the answer, or maybe updating the driver.

Dammit… As I mentioned, my english is lame. When I say that the master-LED flashes, I mean that it stays lit. It doesn’t flash, but it stays lit. Sorry for that. ---

The normal behavir when the S4 is connected (USB) and Tracktor isn’t running is for the USB light to stay lit (not flashing). Flashing probably indicates a connectivity problem with your USB connection. ---
