In theory, USB 3.1 and 3.2 A-ports should provide enough juice to power the Kontrol MK3 keyboards. If you are doing this, please post the specs of the USB-A port and cable/adaptor you are using.

If I understood correctly between the lines of what they wrote, this is not possible. You must use a power brick with the kb to use USB A port on the computer. Or maybe it will work also with a powered hub?
