Hello, I am trying to attach a USB Host Shield on top of an Arduino Leonardo and connect a keyboard to it. However, no power seems to be going to the USB port on the Host Shield. The Host Shield can communicate with the Leonardo — I tested this with a simple code — but when I try to connect a keyboard, even the keyboard’s LED does not turn on.
I watched the “power fix” videos and tested this setup with three different Leonardo boards and three different Host Shields, but the result did not change in any of them.
I would really appreciate it if you could help me.
