Kontrol S2 - USB Light Blinking/Flashing - No connectivity

[kevindavidwilson]

Hello all.

This problem began last night. I set up my Kontrol S2 as normal via USB to my Macbook Pro. The orange USB light on the S2 is just blinking. In addition, when I go to NI USB Audio on my Mac's System Preferences, it displays 'no Native Instruments USB device connected'. I have tried the following and still having the problem:

*updated the driver (Traktor Kontrol S2 1.0.8)
*reinstalled Traktor Pro & drivers (after completely uninstalling Traktor and the drivers using the Mac OS X Uninstaller Utility 1.3.0 found in Utilities on the Support section)
*used another USB lead
*connected it to another laptop (not a Macbook)

Are there any other suggestions? I haven't even updated my Mac recently with new software or anything like that it's just out of the blue. I updated to Mavericks months ago but it has been working fine since then. I am currently on OSX 10.9.

Traktor Pro is playing music fine so I know the software is not an issue.
Any help would be much appreciated.

Thanks,
Kev
