Kontrol S4 problem - Master LED-Light

**Ch1337** · 06-02-2011, 03:41 PM

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.

I think I might've tried everything... :\
Still nothign though...

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?

**Ch1337** · 06-03-2011, 09:38 AM

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

'bump'

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
