M-Audio Oxygen Pro 61 will not work as a Midi Remote controller

My Oxygen works only as a keyboard… not as a controller. It will be shown in the device list as a remote controller, but it will not recognized for this - I can’t add it in the remote-manager. Who can help???
I’ve also tried to configure it as a Machie/HUI remote controller. But this cause also problems.
Any idea how to configure this unit?
