I doubt you can just plug a USB MIDI controller into the Genos, but if you get a special USB-to-MIDI interface to convert the USB-MIDI controller's signals to MIDI, you should be able to connect it to a MIDI In port on the Genos, then I think it should be a simple matter of adjusting your MIDI Receive settings on the Genos. The type of interface I'm talking about is something like a Kenton MIDI USB Host MkII, Sevilla Soft USB Host MIDI 2, Sevilla Soft USB Host MIDI Router, or certain iConnectivity USB MIDI audio interfaces that have the ability to act as a USB Host.
