I have 2 USB shields that I am trying to use on a uno R3 and Lenardo board. I can upload that program and see trouble shooting information in the serial monitor. Unplug the board and install the shield and get no serial output when i plug it back in. Both boards are acting the same way.
The test program I am uploading is from the examples USB Host shield library.
The boards are coming up in the ports in the device manager. Is there anything that needs to be done to the shields to actually make them work? Drivers, jumpers, etc?
