Hi!
I have managed to establish USB-Midi communication between my USB-Midi keyboard and Teensy 4.1 through the USB Host port, I am even powering the keyboard through the Teensy! This is pretty awesome. Everything works fine as long as I am powering the Teensy through the mini-usb, whether from a computer or a wall outlet.
However, if I power the Teensy through the Vin pin, USB Host stops all communication with the midi keyboard. I have verified that my power source has enough power to give to my USB Midi controller by powering the USB port straight from the power source instead of through the teensy, but this still doesn't give me the communication.
Is there something about the USB Host port functionality I am missing here?
Best,
Miro
