[OPEN] CDJ 350 at USB 3.0

Hey,

I got a new samsung ultrabook 940x3g k08 with two usb 3.0 ports.

I have got two cdj 350 and a traktor z2 aswell, everything has the newest firmware installed.

the cdjs are registered in windows, but there are no midi signals received by the cdjs.

I listened with the open source tool MIDI-OX whether the midi signals are parsed by windows, but there are no signals incoming (launhpad and z2 working very well).

CDJs are in control mode and are connected to the computer (i tried both ports an a hub).

I found an article where someone tells to us a usb powered hub, because the usb 3.0 parsing is different to the usb 2.0 parsing.

does anybody of you have / had the same problems?

greetings, Jonas
