CDJ 2000 Nexus HID doesn't work when using XONE K2

Hello,

I am facing an issue when trying to use my CDJ's 2000 nexus with 2 A&H Xone K2 and Traktor Scratch PRO 2.

Indeed when I connect my CDJ's alone to Traktor they offer the Advanced HID feature without any problem.

When I plug my 2 Xone k2's alone they manage to control the 2 decks I mapped them for. (Decks C & D)

But when I plug everything together I do not get the option to use HID on my CDJ's, instead a simple "midi mode" message appears. (For example : 2 CDJ's are working in HID mode, as soon as I plug the K2 they switch to midi)

(Each Controller is working on a different Midi Channel.)

Does anyone know how I could get everything to work (CDJ's in HID and the K2)

Note : I updated the CDJ's to the latest firmware and Traktor is running on the latest version.

Thanks in advance.

Charles.
