I have been working with a microZed board that is connected via jtag to my pc. I have configured the microZed board settings in Vivado 2014.4 for this, but now I want to use a new usb uart connection from my pc to the microZed board in addition to the jtag connection. I have enabled the uart port in Vivado, and installed the driver "Silicon Labs CP210x USB-to-UART" online, but still neither the microZed board or the port is appearing on device manager. Any suggestions?
