Does anyone know what’s the best Usb port to use for my ‘KL Essential 49’? (2.0, 3.0, 3.1, powered, non-powered…)
Welcome. It will make no difference. Originally, powered USB ports on desktop computers were ports that still sent power to their 5V pin even when the computer is switched off, for e.g.: charging attached peripherals.
You can use USB 2, if you want to leave your USB 3 port free for tasks requiring fast data transfer (e.g.: SSD drives, thumb drives). Midi data is so tiny by today’s standards that even USB 1.0 is over-specified.
