Midi from 01v96i

I have install Yamaha steinberg drivers for the Yamaha 01v96i, but plugging midi on the 01v96i connections no signal on computer as Nuendo.
I try to install yamaha usb midi driver and cannot found any midi connection.
01v96i work ok for audio input/output but nothing about midi.
Is necessary another some configuration on the 01v96i?
Thanks your help.

And I found MIDI sinal on 01v96i is blinking.
