I am trying to setup a simple test application that communicates between an external PC and the USB Host port of the Arty-Z7-20. I am able to run the example applications using the PROG UART (J12) on this same board, but for reasons unknown I seem to be unable to have my PC recognize there is an external device attached to J14. Are there any examples or help someone can provide for such a basic test case? To the best of my knowledge I have setup and configured the Arty board to support both UART0 and UART1, so I presume this should not be an issue in my case.
