HiI'm trying to connect a development board. based on MCP2200 USB/UART converter to a High Sierra system. However: I do not see any device appearing in /dev/. The same device does connect to a Windows and Linux system, so I do not suspect the hardware. Is teher ny driver to be installed maybe? The manufacturer claims that the chip supprt the cdc/acm protocol, see site: http://ww1.microchip.com/downloads/en/DeviceDoc/MCP2200_MCP2221_CDC_Mac_Readme.txt
