Connect Usb kb to audya 4 without power supply

Hello
I have audya 4 maybe someone try to connect a usb kb without power supply and without a midi cable?
Only with the usb cable?

Can you ask this question a different way amitayv ?

I also have an Audya 4.
The usb port at the rear of the audya is for connecting your Audya to your computer

Ok i try diffrent
I have maudio keystation 61es kb
Now i use with adapter to turn on the kb
I asked if there is a way to use with the usb cable
As a power supply so i would connect my kb to the audya 4 only with one cable(no adapter and no midi)
Because if i connect the kb to the computer its work the same way without midi and without addapter only one cable .
So it is possibale to do that?
Thanks

Yes, but it won't communicate properly with your controller. If you connect to the front ports (USB-DEVICE), these will power your controller, but these ports are not designed to communicate with a controler ... just storage devices.

If you connect to the back USB port, make sure you set the MENU - MIDI- USB = Midi.

Thanks,

AJ or amitayv

how would you connect a keyboard controller to AUDYA if they BOTH have the same Type B female connector ?
