I was looking for a pure C/C++ way to control this mcp2221.
I wonder if adafruit board will work without any tricks with your code and generally with mcp2221 dlls.
which board did you use?

Would it be possible to implement a USB-to-UART bridge that shows up on USB-CDC similar to how the MCP2221a has the USB-HID and USB-CDC which maps the TX and RX pins to /dev/ttyACM0 on your laptop?
