I just recently got a USB Host Shield and installed it onto my Leonardo. When I take the USB Host Shield off the Leonardo the COM port opens back up so I can see it, but when I put the USB Host Shield back on it is non-existent to my PC. Does anyone know what could be causing this issue?
This might help.
Thanks, for the response! Sadly I'm still having problems, the Leonardo shows up on my IDE now, but the USB on the Host Shield doesn't seem to be getting power. I tried to link the 5V and VBUS as well but it doesn't appear to be working...
